Kinematics

A car is moving at a constant velocity. Which of the following motion diagrams best represents this motion?

Which of the following narrative descriptions of motion corresponds to an object moving to the right at a constant speed, then suddenly reversing direction and moving to the left at the same constant speed?

A car starts from rest and accelerates at a constant rate of 2 , m/s^2 for 5 seconds. What is the final velocity of the car?

An object is thrown vertically upwards with an initial velocity of 20 , m/s. What is the maximum height reached by the object? (Use $g = 10 , m/s^2$)

An object is thrown vertically upwards with an initial velocity. It reaches a height of $h$ at time $t_1$ on the way up and again at time $t_2$ on the way down. What is the initial velocity of the object?

A ball is thrown with an initial velocity of 15 , m/s and experiences a constant acceleration of $-3 , m/s^2$. What is the displacement of the ball after 4 seconds?

A position vs. time graph shows a curved line. How can you estimate the instantaneous velocity at a specific point on the curve?

A skateboarder starts from rest and accelerates down a ramp. Which motion diagram corresponds to this scenario?

A ball is dropped from a height of 20 m. Assuming no air resistance, what is the velocity of the ball after 1 second? (Use $g = 10 , m/s^2$)

A position vs. time graph shows a straight line from (0,0) to (4, 8). What is the average velocity of the object over this time interval?
