A car is traveling at 7.1m/s accelerates 4.3 m/s^2 to reach a speed of 16.0 m/s how long does it take for this acceleration to occur

Answer

2.06977 seconds

Explanation

Acceleration, a, is the rate of change of velocity

a = (v-u) / t

where v and u are final and initial velocities respectively.

4.3 = (16.0 - 7.1) / t

4.3 = 8.9/t

t = 8.9/4.3

= 2.06977 seconds
