A stone is thrown vertically upward with an initial speed of 20 m/s. When it returns, it falls into a hole that is 10.0 m deep. How long (in seconds) is the rock in the air, from the instant it is tossed until it hits the bottom of the hole? Use -9.80 m/s2 for the local acceleration due to gravity and assume no significant air resistance

A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval? (Hint: You can ignore the effects due to gravity
A stone is thrown vertically upward with an initial speed of 20 m/s. When it returns, it fall into a hole that is 6.0 m deep. What is the velocity of the rock (in m/s) when it hits the bottom of the hole? Use -9.80 m/s2 for the local acceleration due to gravity and assume no significant air resistance. Assume that the y axis is positive in the up direction.

A hot-air balloon is drifting in level flight due east at 3.0 m/s due to a light wind. The pilot suddenly notices that the balloon must gain 20 m of altitude in order to clear the top of a hill 130 m to the east. How much time does the pilot have to make the altitude change without crashing into the hill? What minimum, constant, upward acceleration is needed in order to clear the hill?
A taxi traveling along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 33.0 m/s. Then the vehicle travels for 47.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the taxi in motion (in s)? Answer:_____________s (b) What is the average velocity of the taxi for the motion described? (Enter the magnitude in m/s.) Answer:______________m/s
One ball is dropped at rest from a height of h = 75 m. At the same time, another ball is thrown upward from the ground with initial velocity v2 = 34 m/s. It takes Δt time for them to meet on the way. Defining the positive direction going upward, what is the acceleration of the two balls, a in m/s2? Express the displacement of the ball falling down, Δy1, when the two balls meet in terms of Δt and a. Express the displacement of the ball going upward, Δy2, when the two balls meet in terms of v2, a, and Δt. Express h in terms of Δy1 and Δy2. Calculate the numerical value of Δy2, in meters, which represents the height at which the two balls meet.
