A car is moving at a velocity of 36km/h. After 10s, the
velocity becomes 54km/h. Assuming that the change in
velocity took place at a uniform rate, find the acceleration.

Answer:
initial velocity (u) = 36 km/hr = 10 m/s
final velocity (v) = 54 km/hr = 15 m/s
time taken (t) = 10 seconds
acceleration (a) = ?
solution :
v = u+at
15 = 10 + (a) 10
10 + 10a = 15
10a = 15 - 10
10a = 5
a = 5/10
a = 0.5 m/s^2
This is your answer

Answer:
initial velocity (u) = 36 km/hr = 10 m/s
final velocity (v) = 54 km/hr = 15 m/s
time taken (t) = 10 seconds
acceleration (a) = ?
using 1st law of motion
v = u + at
15 = 10 + (a) 10
10 + 10a = 15
10a = 15 - 10
10a = 5
a = 5/10
a = 0.5 m/s^2
