Practice-4 on Speed, Velocity, and Acceleration

Question 1: A ball is projected upward. Eventually, after the ball reaches its maximum height, it will fall back.
Indicate which statement is correct.
Question 2: Assume a student throws a ball vertically downward with a velocity of 10 m/s.
If air friction is considered negligable then calculate the speed of the ball one second later.
Question 3: Suppose you throw a ball vertically with a velocity of 10 m/s.
Approximately, when will it reach its highest height?
Question 4: Assume a television screen fall down from rest at a great height.
Calculate the speed after it has fallen for 5 seconds where air resistance is considered negligible.
Question 5: Assume a box of 5 kg is dropped from a building and hits the ground in 7 s.
Calculate the time it takes for a 10-kg box to hit the ground where air resistance is considered negligible.
Question 6: If a rocket is fired from a fighter jet and assuming that air resistance is negligible.
Which statement is correct about the rocket.
Question 7: If you throw a ball up in the air.
Indicate the status of the ball when it reaches its highest point.
Question 8: If you throw a ball up in the air with an initial velocity of 20m/s.
Calculate the ball's velocity after 4 seconds.
