As shown in the figure below, two masses m, = 5.20 kg and m, which has a mass 75.0% that of m,, are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m, and m, start from rest, a distance h = 2.60 m, use energy content to determine the following.

A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (whileignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance fromyou, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180g) with an initial velocity of 1009 m/s at a fixed angle α, where sin α=3/5 and cos α= 4/5. (g = 9.8 m/s2) d. Provided that the collision is inelastic, calculate the speed after the collision.e. Calculate the height the two objects taken from the impact up to the maximum height before it startsfalling to the ground.
Two blocks with masses m1 = 5.0 kg and m2 = 7.0 kg are attached by a string as shown in the figure below, over a pulley with mass M = 2.0 kg. The blocks are released from rest. The pulley, which turns on a frictionless axle, is a hollow cylinder with radius 0.050 m over which the string moves without slipping. The horizontal surface is frictionless. Find the speed of the system when the block of mass m2 has dropped 2 m.
