Question

b. A truck starts to move from rest. If it gains the acceleration of
3m/s2 in 5 sec, calculate the final velocity and distance covered by
the truck. (2)​

Answer 1

Given :-

A  truck starts to move from rest. If it gains the acceleration of

3m/s2 in 5 sec,

To Find :-

Final Velocity

Distance covered

Solution :-

v = u + at

v = 0 + 3(5)

v = 0 + 15

v = 15 m/s

Now

s = ut + 1/2at²

s = 0(5) + 1/2(3)(5)²

s = 0 + 1/2(3)(25)

s = 0 + 1/2 × 75

s = 75/2

s = 37.5 m
