Question

A car is travelling intially at 7 m/sec accelerates at the rate of 8.0 m/sec.for an interval of 2 sec ....what is its velocity at the end of 2 sec

Answer 1

We have
u = 7 m/ s
a = 8 m / s^2
t = 2sec
v = ?

We know that

v = u + at
v = 7 + 8 × 2
v = 7 + 16
v = 23
Velocity after 2 s is 23 m / s
