A ball is thrown upward with an initial velocity of 20m/s. How long will the ball take to reach its maximum height?

An airplane lands on a runway with a velocity of 150m/s. How far will it travel until it stops if its rate of deceleration is constant at \(-3m/s^{2}\)?

A ball is thrown downward from the top of a roof with a speed of 25 m/s. After 2 s, its velocity will be

A rocket is propelled upward with an acceleration of \(25m/s^{2}\) for 5 s. After that time, the engine is shut off, and the rocket continues to move upward. The maximum height, in meters, that the rocket will reach is

An object has an initial velocity of 15 m/s. How long must it accelerate at a constant rate of 3 \(m/s^{2}\) before its average velocity is equal to twice its initial velocity?

A projectile is launched at an angle of \(45^{0}\) with a velocity of 250 m/s. If air resistance is neglected, the magnitude of the horizontal velocity of the projectile at the time it reaches maximum altitude is equal to

A projectile is launched horizontally with a velocity of 25 m/s from the top of a 75m height. How many seconds will the projectile take to reach the bottom?

At a launch angle of \(45^{0}\), the range of a launched projectile is given by

A projectile is launched at a certain angle. After 4 s, it hits the top of a building 500 m away. The height of the building is 50 m. The projectile was launched at an angle of

A mass attached to a string is twirled overhead in a horizontal circle of radius R every 0.3 s. the path is directly 0.5m above the ground. When released, the mass lands 2.6 m away. What was the velocity of the mass when it was released and what was the radius of the circular path?
