Two identical stones are dropped from rest and feel no air resistance as they fall. Stone A is dropped from height h, and stone B is dropped from height 2h. If stone A takes time t to reach the ground, stone B will take time

A car moves along the x-axis with constant speed, the acceleration of the car is:

The position of an object as a function of time is given by x = bt² - ct. where b = 2.0 m/s² and c = 6.7 m/s, and x and t are in SI units. What is the instantaneous velocity of the object when t = 3.3?

A ball is thrown directly award and experiences no resistance Which one of the following statements about its motion is correct?

The following are equations of the velocity v(t) of a particle. In which situation the acceleration is constant?

A dragster starts from (rest and travels 1/4 mi in 7.30 s with constant acceleration. What is its velocity when it crosses the finish line?

A car accelerates from 5 m/s to 21.0 m/s) at a rate of 3.00 m/s². How far does the car travel while accelerating?

A ball is dropped vertically_downwards from a heighth. If the ball reaches a height of 30 m above the ground in 2 s, the height h is:

A particle moves with initial velocity 3m/s and acceleration of 2 m/s², the distance it traveled in 5 s

A ball is thrown vertically upward at a speed of 13.72 m/s. It will reach its maximum height in:

A particle moves in the positive x-direction with increasing speed. Its velocity and acceleration are such that:

A boy shot a foot ball vertically up with an initial speed Vo. When the ball was 2 m above the ground, the speed was 0.8 of the initial speed. The initial speed is:

A particle starts motion at 10 m/s. If it moves 30 m in 5 s, its final velocity is:

A package is dropped from a helicopter moving upward at 15 m/s. If it takes 29 s before the package strikes the ground, how high above the ground was the package when it was released if air resistance is negligible?

The position of an object is given by x = at³ - bt²+ ct,where a = 4.1 m/s³, b = 2.2 m/s², c = 1.7 m/s, and x and t are in SI units. What is the instantaneous acceleration of the object when t = 3.3 s?
