A car travels 150 meters in 5 seconds. What is the average speed of the car?

Average speed = Total distance / Total time = 150 m / 5 s = 30 m/s.

500

A cyclist travels 200 meters north in 10 seconds and then turns around and travels 50 meters south in 2 seconds. What is the total distance traveled and the displacement?

Total distance = 200 m + 50 m = 250 m; Displacement = 200 m - 50 m = 150 m north.

A box with a mass of 10 kg is pushed with a force of 40 N. If the frictional force opposing the motion is 10 N, what is the acceleration of the box?

Net force = Applied force - Frictional force = 40 N - 10 N = 30 N. Acceleration = Net force / Mass = 30 N / 10 kg = 3 m/s².
