Answer to Question #212022 in Mechanics | Relativity for Kelvine

Question

1. A car traveling 36km/hr accelerates uniformly at 2m/s.calculate the velocity after 5s

Answer 1

Gives

t=5sec

acceleration (a)=2m/sec

$$u=36km/h=\frac{36\times10^{3}}{3600}=10m/sec$$

V=?

We know that

$$v=u+at=10+2\times5=20m/sec$$

$v=20m/sec$
