The velocity of a car at different times is recorded in the table below. Use the data to calculate the car’s average acceleration and total displacement after 8 seconds.

Average acceleration = 2.0 m/s², Displacement = 60 m Average acceleration = 2.5 m/s², Displacement = 100 m Average acceleration = 2.5 m/s², Displacement = 80 m Average acceleration = 3.0 m/s², Displacement = 120 m

Velocity is defined as:

Acceleration per unit time Displacement per unit time Rate of change of distance Speed without direction

A body moves with constant velocity. Its acceleration is:

Constant Increasing Negative Zero

A proton is projected straight up at 20 m/s in a region where a uniform electric field produces a downward acceleration equal to 10 m/s². Calculate the total time of flight.

2 s 3 s 4 s 5 s

From a velocity-time graph, the area under the line represents:

Acceleration Displacement Force Speed

A particle moves along a circular path of radius 10 m at 15 m/s for 10 s, then accelerates uniformly to 25 m/s over 10 s, and finally slows uniformly to rest in 5 s. Calculate the total distance along the path. Also, calculate the centripetal acceleration at its maximum speed using the formula a = v²/r.
