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.
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.
DISTANCE, TIME, SPEED PRACTICE PROBLEMS YOU MUST SHOW YOUR WORK. You can use a calculator but you must show all of the steps involved in doing the problem. SPEED 1. If a car travels 400m in 20 seconds how fast is it going? 2. If you move 50 meters in 10 seconds, what is your speed? 3.
path. First, find the time at which the ball reaches its maximum height, v yf = v 0y + a yt 0 = 24 + (−10)t max ⇒t max = 2.4s where v yf is the ball’s velocity at the end of the upgoing path where it is zero. Now that the maximum time is found, substitute it into the following equation All Rights Reserved. Page 6
body has travelled by the time it has taken; the speed may vary from moment to moment during this time. The instantaneous speed is the speed at which the body is travelling at a moment in time. gradient = distance _____ time = 8 m _____ 0.25 s = 32 m/s b Speed is a scalar quantity – it is distance travelled divided by time without regard to ...
Position-time (!⃑-t) graphs show an object’s _____ as a function of time. Independent variable (x-axis) is _________________. The dependent variable (y-axis)is __________________.
Kristina’s journey is shown on the distance-time graph below. (a) Work out Kristina’s average speed, in kilometres per hour. (b) Use the information to plot Lucas’s journey on the same distance-time graph.
