Question

A car leaves the rest and accelerates evenly for 10 s, reaching a speed of 20 m/s.

calculate the cars acceleration? How many meters did the car travel

Answer 1

acceleration = 2m/s^2

distance= 100 meters

Step-by-step explanation:

acceleration = (final velocity - initial velocity) / time

acceleration = (20 m/s - 0 m/s) / 10 s

-----------------------------------------------------------------------------------

distance = (initial velocity * time) + (0.5 * acceleration * time^2)

since the car starts from rest, the initial velocity is 0.

distance = 0.5 * 2 m/s^2 * (10 s)^2
