Question

A car changes its velocity from 45 km/h to 65 km/h in 3 s. Find the magnitude of its acceleration

Answer 1

Answer:Answer:

1.85m/s

Step-by-step explanation:

initial velocity = 45km/h

final velocity = 65km/h

time = 3 minutes

we change that 45km/h is 12.5 m/s and 65km/h is 18.05 m/s

Formula:

acceleration = (final velocity - initial velocity)/time

Solution:

18.05-12.5=1.85m/s
