  1. Speed and Velocity Practice Worksheet. 1. Megan rolls a ball down a ramp until the ball hits the wall. The ramp is 2.5 m long and the distance from the end of the ramp to the wall is 1.5 m. If it took 0.5 seconds for the ball to hit the wall then what is the ball’s speed?

  2. Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.

  3. Speed is the answer to the question, 'How fast?' Velocity is speed with direction. Speed (velocity) is the rate of change of distance (displacement) with time.

  4. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.

  5. The velocity-time graph below shows the run of a sprinter. (a) What was the sprinter’s maximum speed? (b) Use the graph to find the sprinter’s acceleration between 0 and 10 seconds.

  6. Solutions to the problems on velocity and speed of moving objects. More tutorials can be found in this website. Problem 1: A man walks 7 km in 2 hours and 2 km in 1 hour in the same direction. a) What is the man's average speed for the whole journey? b) What is the man's average velocity for the whole journey? Solution to Problem 1: a) b)

  7. Questions about velocity. There are at least two ways to determine the velocity just before the parachute opened. One would be to use the fact stated in the stem of the problem — that the skydiver was in free fall. We could use the first equation of motion for an object with a constant acceleration.
