PHYSICS 1, EAST LA COLLEGE TEST #4 Review (Ch 9 - 10), Mr. V. Kiledjian 1) A 5 kg block is moving in the x-direction at an initial velocity of 6 m/s when a force, F = t 2 + t 3 Newtons is applied to the object in the x-direction for t = 2 seconds. a) What is the impulse imparted to the object, its final momentum, velocity, and the work done on the object? b) Answer the same questions above if the mass of the object is decreasing by 1 kg/sec. 2) A 2 kg block is moving East bound at an unknown speed V i and a 4 kg block is moving South bound at 3 m/s. They collide perfectly inelastically and move at an angle of 26 degrees South of East. a) Find V i b) Find the % loss of K.E. 3) A 2 kg block is moving at 5 m/s to the right and a 3 kg block is moving at 2 m/s to the left and they collide perfectly elastically. They are in contact for 0.085 seconds. a) Find the final velocity of each block b) Find the impulse imparted to each block and the force of contact between each other 4) Imagine the bocks in problem 3 to be balls. They collide Semi-elastically in 2 dimensions. The final velocity of the 2 kg ball is 2 m/s at 33 degrees above the horizontal.
