A car moves with an initial velocity of 25ms-1 and reaches a velocity of 45-1 in 10s. What is the acceleration of the car?
acceleration=
(final velocity-initial velocity)/time
10
25
To find the acceleration of the car, we can use the formula:
acceleration (a) = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 25 m/s
Final velocity (v) = 45 m/s
Time (t) = 10 s
Substituting the values into the formula:
a = (v - u) / t
a = (45 - 25) / 10
a = 20 / 10
a = 2 m/s²
Therefore, the acceleration of the car is 2 m/s².
