Displacement
What is the difference between distance and displacement?
Distance is total length covered while displacement is the distance from point A to point B in a straight line.
A cyclist begins a training ride and covers a total distance of 1800 meters in exactly 45 seconds. What is the cyclist's average velocity in meters per second (m/s)?
40 m/s
A sports car accelerates uniformly from an initial velocity of 10 m/s to a final velocity of 35 m/s over a period of 5.0 seconds. What is the car's constant acceleration in m/s^2?
5 m/s^2
What is the displacement if a car that goes from 0m to 100m.
+100m
A high-speed maglev train travels at a constant velocity of 150 meters per second (m/s) through a tunnel. If the train maintains this velocity for 7.5 seconds, what distance does it cover during that time?
1125 m
A commercial jet accelerates down a runway starting from rest at a constant rate of 3.5 m/s^2. How much time in seconds does it take for the jet to reach its takeoff velocity of 80 m/s?
22.6 sec
What is the displacement of a runner that goes around a track 3 times and starts and stops at the finish line.
0m
A commercial airplane is maintaining a cruise velocity of 250 meters per second (m/s). How much time in seconds will it take the plane to travel between two cities that are 1,000,000 meters (1,000 km) apart?
4000 sec
A subway train is leaving a station. It increases its speed from an initial velocity of 2.5 m/s to a final velocity of 20.5 m/s in a total duration of 12 seconds. What is the train's constant acceleration in m/s^2?
1.5 m/s^2
What is the displacement of a bug that goes from the 15cm mark on a ruler to the 3cm mark.
-12cm
A marathon runner completes a distance of 12,600 meters in a time of exactly 50 minutes. What is the runner's average velocity in meters per second (m/s)?
4.2 m/s
A sled rider begins decelerating at a rate of −1.5 m/s^2 as they reach the bottom of a hill. They decelerate for 6.0 seconds and come to a final stop (vf=0 m/s). What was the rider's initial velocity at the moment they began decelerating?
9 m/s
What is the displacement of a boat that went 138m east, 29m west, 51 m east again, then finally 102m west?
58m east
An autonomous delivery drone flies a route covering 36 kilometers (km). If the drone finishes the route in 2 hours, what is its average velocity in meters per second (m/s)?
5 m/s
A falling rock accelerates due to gravity at a rate of 9.8 m/s^2. If the rock is dropped from rest (vi=0 m/s) and falls for 4.5 seconds, what will be its final velocity just before it hits the ground?
44.1 m/s
