Answer: 2 on a question an object was dropped with a mass of 2.45 kg at height of 5.2 m. calculate for its potential energy at height of 3m with respect to the ground what is it's KE? - the answers to freedukasyon.com. Linear momentum = mass × velocity. Velocity =. V = = 0.5 ms -1. Question 2. A door is pushed, at a point, whose distance from the hinges is 90 cm, with a force of 40 N. Calculate the moment of the force about the hinges. Solution: Formula: The moment of a force M = F × d. Given: F = 40 N and d = 90 cm = 0.9 m. This problem has been solved! 1. An object of mass 2 kg is dropped from rest at an initial height of 500 m and we assume the air resistance is equal to half the instantaneous velocity. Find the velocity v and distance s of the object as functions of time. 2. suppose that in a simple circuit the resistance is 12 Ω and the inductance is 4 H. Calculate the gravitational force between a body of mass 100 kg and the earth. Also calculate the acceleration produced in the body and that in earth. 19. A body weighs 1 kg on the surface of the moon. If mass of the moon is 7.4 x 10 22 kg and radius of moon is 1740 km. Calculate: a. Jun 30, 2021 · Question 1: A mass of 2Kg is taken from the ground to the height of 10m. Find the potential energy of the object. Answer: The potential energy of a mass ‘m’ at the height ‘h’ is given by, P = mgh . Given: m = 2kg and g = 10 m/s 2 and h = 10m. Aim: Find the potential energy. Plugging in the values in the formula. P = mgh . ⇒ P = (2)(10 .... (a) 0.0250 kg•m2 (b) 0.0500 kg•m2 √ (c) 0.0750 kg•m2 (d) 0.100 kg•m2 (e) none of the above 1 2 𝑅2). It is mounted on a horizontal frictionless axle that passes through its center. A light rope is wrapped around the rim of the disk and a block of mass 4.00 kg is suspended from the free end of the rope as shown. The system is released. Weight/Force is the gravity on an object, the formula is: W = m × g Where: W: Weight/Force, in N m: Mass of the object, in kg g: Gravity, in m/s^2. m 2 =200 g=0.2 kg . μ k =0.5 . h=10 cm=0.1 m . v 1 top =0 m/s . ... Gravitational Potential Energy depends upon an object's mass m, height h, and gravity g. ... will a 200g block travel with a coefficient of kinetic friction of 0.5 after being hit by a 100g block on a pendulum dropped from a height of 10 cm? How will the height h affect the. The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g. The simple pendulum equation is: T = 2π * √L/g. Where: T: Period of the simple pendulum. L: Length of the pendulum. 3) 100 J 4) 50 J 8. What distance did the object travel in moving from point A to point B? 1) 2.5 m 2) 10. m 3) 20. m 4) 100 m 9. Compared to the impulse required to stop the object at point B, the impulse required to stop the object at point C is 1) less 2) greater 3) the same 10. The object comes to rest at a vertical height of S (point D. 74AP. An object of mass 10 kg is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. (See below.) The spring constant is 500 M/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless.. The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g. The simple pendulum equation is: T = 2π * √L/g. Where: T: Period of the simple pendulum. L: Length of the pendulum. = 105 cm 19 Mass 500 mg 0.001 g (1 mg) 1 kg (1000 g) or 1 g = 1000 mg or 1 g = 0.001 kg = 5.00 x 10-4 kg Example: How many kilograms are contained in 500 milligrams? Mass: The amount of matter that an object possesses -- standard metric system unit (SI unit) is the kilogram (kg) -- 1 kg of mass is contained in an object that weighs 2.2 lbs. A block of mass 5 kg is placed on top of a block of mass 10 kg, which in turn sits on a frictionless horizontal surface, as shown in the figure. A force F = 98 N is applied to the 10 kg block, and the 5 kg block is held in place by a string attached to the wall. The coefficient of friction between the two blocks is 0.15. A ball of mass m is dropped from a height h above the ground. (A) Neglecting air resistance, determine the speed of the ball when it is at a ... A block of mass 1.6 kg is attached to a horizontal spring that has a force constant of 1000 N/m. The spring is compressed 2.0 cm and is then released.
