A 5.00 kg block is released from rest on a ramp that is inclined at an angle of 60.0° below the horizontal. The initial position of the block is a vertical distance of 2.00 m above the bottom of the ramp. (a) If the speed of the block is 5.00 m/s when it reaches the bottom of the ramp, what was the work done on it by the friction force? (b) If the angle of the ramp is changed but the block is released from a point that is still 2.00 m above the base of the ramp, both the magnitude of the friction force and the distance along the ramp that the block travels change. If the angle of the incline is changed to 50.0°, does the magnitude of the work done by the friction force increase or decrease compared to the value calculated in part (a)? (c) How much work is done by friction when the ramp angle is 50.0°?

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.
