Acar can accelerate from a standstill to 100 km/h [e] in 9.60s. calculate the average acceleration

Acceleration is :

a = 2.89 m/s2

Explanation:

Acceleration : It is the change in the velocity of the object per unit time.

The object starts from the rest , so the initial velocity of the object is zero.

Initial velocity , u = 0

Final velocity = 100 km/h

Change the velocity to m/s because[ time unit is in second(9.60 s)]

1 km = 1000 m

1 hour = 60 x 60 sec = 3600 sec

v = 27.78 m/s

u = 0 m/s

time = 9.60 s

The acceleration"a" is calculated using :
