Question

a car moves with a speef of 5m/s and comes to rest after10s. caliculate initial velocity

Answer 1

Hey

Initial velocity (u) = 5 m/s

Final velocity (v) = 0 m/s

time (t) = 10 sec

Acceleration = ?

We apply 1st equation of motion :
v = u + at

0 = 5 + a (10)

-5 = a(10)

a = -1/2 m/s² Answer.
