A stone thrown from the top of a building is given an initial velocity of 25 m/s straight upward. The building is 70 m high, and the stone just misses the edge of the roof on its way down, as shown in Figure (1). Using tą=0 as the time the stone leaves the thrower's hand at position A, determine: (A) The time at which the stone reaches its maximum height, (B) The maximum height, (C) The time at which the stone returns to the height from which it was thrown, (D) The velocity of the stone at this instant, and (E) The velocity and position of the stone at t= 5 s.

To find the maximum velocity of two dump trucks connected by a cable. As shown, two dump trucks are connected by a cable. One truck (Truck 1) is loaded, has a maximum engine power P , and is able to attain a maximum speed of v. Another truck (Truck 2) has a maximum engine power 2P and can attain a maximum speed of 1.5v. To solve this problem, assume that each truck, when not attached to the other truck, has a speed that is limited only by wind resistance. Also assume the following: The wind resistance is a constant force (although a different constant for each truck). Therefore, it is independent of a truck’s speed. The wind resistance force on each truck is the same before and after the cable is connected. The power that a truck's engine can generate is independent of that truck's speed. Find vmax, the maximum speed of the two trucks when they are connected. Assume that both engines are running at maximum power. Express your answer in terms of v.

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.
