The time taken for overtaking with constant speed is 5s.
What is speed?
The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.
Given is a car starts from rest at constant acceleration of 2.0 m/s². At the same instant a truck travelling with a constant speed of 10 m/s overtakes and passes the car.
Using the first equation of motion, we have
v =u +at
Where v = final speed = 10 m/s,
u = initial speed = 0 m/s
acceleration a = 2.0 m/s²
Substituting the values, we get
10 = 0 + 2t
t = 5s
Thus, the time taken is 5s.
