A man was standing on one side of the roof of a building 145 meters above the ground and shot a projectile with an initial speed of 53 m/s at an angle 30.0 degrees with the horizontal. Find the time (seconds) it took the projectile to hit the ground. How far (meters) away from the base pf the building did the projectile land. Find the vertical and horizontal components of the velocity (m/s). What is the velocity in m/s

Figure 4 shows a trolley of mass 6.12 kg passing through point A with a velocity of 6 m/s. It slides down a rail to point C. From A to C, 250 J of energy is lost due to friction. What is the equation used to find the velocity of the trolley at point C ?
Graph below represents the force on a 12 kg air mass as it passes through a jet engine. Immediately after entering the engine, the force is 9,039 N, and the force tapers linearly to zero once the air reaches the back of the engine 2.3 m later. If the air enters the engine with velocity 252 m/s, what is its exit velocity? (Please answer to the fourth decimal place - i.e 14.3225)

A stone is dropped from a balloon that is ascending at uniform rate of 10 m/sec. If it takes the stone 10 sec. to reach the ground, how high was the balloon at the instant the stone was dropped?
In a rope-climbing competition, all of the lifting is done by the arms; legs can only dangle. Imagine 220-lb Garvin Smith in training, hanging stationary from the rope, his legs off the floor. When prompted by his coach, he rapidly lifts his center of mass by 4 ft. in 0.65 s. Calculate Garvin Smith's acceleration. Round the final answer to one decimal place. Determine the net force (“force imbalance”) producing the acceleration. Round the final answer to one decimal place. Which forces are acting on Smith? (Note that his arms are part of himself, so they cannot exert a force on Smith.) With what magnitude force is Smith pulling down on the rope? Round the final answer to one decimal place. The force of 130.2 lb points _____.
