🚀 Kinematics — Unit Quiz

A car travels 60 km east, then 20 km west. What is the magnitude of its displacement?

A runner completes a 400 m lap around a circular track and returns to the starting point. Which statement is correct?

An object moves with constant velocity of +6 m/s. What is its acceleration?

A position-time graph shows a straight line with a steep positive slope. This represents an object that is:

A car traveling at constant velocity on a straight road — select ALL true statements.

An object has a negative velocity and a positive acceleration. What is happening?

A ball is thrown straight up with initial speed 20 m/s. How long does it take to reach the highest point? (g = 10 m/s²)

A car starts from rest and reaches 30 m/s in 6 s. Using the kinematic equations, how far does it travel during those 6 s?

A ball is thrown upward and returns to its launch point. Select ALL correct statements about the ball at the instant it reaches the highest point.

A projectile is launched horizontally from a cliff. Which statement about its motion is correct?

A ball is kicked horizontally at 15 m/s from the top of a 45 m cliff. What is the magnitude of the ball's velocity just before it hits the ground? (g = 10 m/s²)

Velocity-time graph analysis: An object's v-t graph shows a straight line from (0 s, 8 m/s) to (4 s, −4 m/s). What is the displacement during this interval?

A projectile is launched at 40 m/s at 30° above horizontal. Select ALL correct statements. (g = 10 m/s², sin 30° = 0.5, cos 30° = 0.87)

A stone is thrown horizontally from a bridge at 12 m/s. It hits the water 3.6 s later. (a) How high is the bridge above the water? (b) How far horizontally from the bridge does the stone land? (c) What is the stone's speed when it hits the water? (g = 10 m/s²)

A train accelerates from rest at 2 m/s² for 10 seconds, then travels at constant velocity for 20 seconds, then brakes uniformly to a stop in 5 seconds. (a) Sketch a v-t graph of the full journey. (b) Calculate the total distance traveled.
