A stone thrown horizontally with a spewed of 22m/s from the top of a should I call Cliff at the edge of a lake. If the stone hits the water 4.00s later the height of the cliff is closer to  90 m 80m 100m 110m

Without air resistance, the time for a vertically tossed ball to return to where it was thrown is more than the time going upward. O less than the time going upward. O the same as the time going upward. O 9.81 m/s for every second in the air.

A projectile is launched horizontally off from a tall building at a sped of 50m/s. After three seconds, the speed of the projectile is closest to b O c Od 40 m/s 50 m/s 60 m/s 30 m/s

A football is thrown by a quarterback (from shoulder level) to a receiver downfield, who catches it at shoulder level. At what point is the ball's speed at a minimum? (assume air resistance to be negligible). A. (a) just after leaving the quarterback's hand. B. (b) just before arriving at the receiver's hand. C. (c) at the top of the trajectory. D. (d) the speed is constant throughout the entire trajectory.
