Answer:
The acceleration of the object will be 4m/s²
Explanation:
Initial velocity, u = 0m/s(Body starts from a state of rest)
Final velocity, v = 40m/s
Time, t = 10s
∴ Acceleration, a = Change in velocity/Time
a = (v - u)/t
a = (40 - 0)/10
a = 40/10
a = 4m/s²
Therefore acceleration of the object after 10s will be 4m/s².
