4. It takes a car one minute to go from rest

to 30 m/s east. What is the acceleration of

this car

0.5m/s2

Explanation:

Data obtained from the question include:

u (initial velocity) = 0m/s

v (final velocity) = 30m/s

t (time) = 1min = 60secs

a (Acceleration) = ?

a = v - u/t

a = 30-0 / 60

a = 30/60

a = 0.5m/s2
