A stone is thrown horizontally from the top of a cliff. A quarter of a second after leaving your hand it drops vertical distance of ___ m from the release point.  Express you answer to 2 significant figures. The stone is in free fall, g = 10 m/s2

A ball is launched vertically upward with a speed of (21.0+A) m/s. Determine the speed of the ball when it has reached a height of (18.0 + B) m above the launch position. Give your answer in m/s and round the answer to three significant figures. A=15 B=8

A rock is tossed from the top of a building at an angle of 35° above the horizontal with an initial speed of 16 m/s. The rock lands on the ground 2.8 s after it is tossed. What is the height of the building (in m)?

The froghopper, Philaenus spumarius, holds the world record for insect jumps. When leaping at an angle of 58.0degrees above the horizontal, some of the tiny critters have reached a maximum height of 56.7 cm above the level ground. A)What was the takeoff speed for such a leap? B)What horizontal distance did the froghopper cover for this world-record leap?

A ball on a porch rolls 60 cm to the porch’s edge, drops 40 cm, continues rolling on the grass, and eventually stops 80 cm from the porch’s edge. What is the magnitude of the ball’s net displacement, in centimeters?

Please assist with this question with details on how to do it. Thank you.  Mayan kings and many school sports team are named for the puma, cougar, or mountain lion - felis concolor- the best jumper among animals. It can jump to a height of 12 ft when leaving the ground at an angle of 45 degrees. With the speed , in SI units, does it leave the ground to make this leap?

A baseball is hit almost straight up into the air with a speed of 24 m/s . Estimate how long it is in the air. Express your answer to three significant figures and include the appropriate units.

A skydiver falls d1=355m in t1=8.7s before opening her parachute. After the chute opens, she falls an additional d2=780m in t2=116s. Calculate the skydiver’s average speed, v avg in meters per second, during the entire fall.

An airplane takes off and flies upward at an angle of 21° with a constant speed of 262 m/s. While the plane is flying upward, a piece of the engine falls off when the plane reaches a height of 860 m. a) How long does it take the piece of the engine to reach the ground? Give your answer in seconds. b) What is the horizontal distance covered by the piece of the engine before it lands? Give your answer in meters.

A ball thrown horizontally from a height of 1.2m hits the ground at a distance of 5.0m. What was the initial speed of the ball (in m/s)?
