Two objects, A and B, have the same size and shape. Object A is twice as massive as B. The objects are simultaneously dropped from a high window on a tall building. (Neglect the effect air resistance.) And the objects reach the ground at the same time. Which of the following will be greater for object A? When a mass M experiences a velocity change of v in a time of t, it experiences a force of F. Assuming the same velocity change of v, how will the force experienced by a mass of M/2 in a time of 4t b affected? A 3000 kg truck collides with a 1500 kg car and causes a lot of damage to the car. A lot of damage is done on the car. Which of the following statements is correct? In a physics lab, a 0.500 kg cart moving at 36.4 cm/s collides inelastically with a second cart which is initially at rest. The two carts move together with a speed of 21.8 cm/s after the collision. What is the mass of the second cart? A car of mass 1500 kg travelling at 70 km/h has its speed reduced to 30 km/h by a constant breaking force over a distance of 125 m. What is the change in kinetic energy of the system? The potential energy of an object at a certain height is 350 J. What is the kinetic energy possessed by the object when it just touches the surface of the earth? A. An object of mass 1.2 x 10³ g is kicked vertically upward from the ground with a velocity of 1.50 x 10 mm/minute.
