An object initially at rest experiences an acceleration of 9.8 m/s2. How much time will it take it to achieve a velocity of 58 m/s?
5.9 seconds
A student walked 11 meters East, before hearing a friend, turning, and walking 18 meters West.
What was the total distance the student traveled?
What was their displacement? Include direction with their displacement.
Distance = 29 m
Displacement = 7 m, West
