Rectilinear Motion

Question

A body is projected vertically upwards with a velocity of 19.6m/s. Then the maximum height reached by the body…..

Easy

A

39.6m
B

24.5m
C

19.6m
D

39.2m

Solution

Given that initial speed $u = 19.6 m / s$
$∴$ The maximum height $H = \frac{u^{2}}{2 g}$
$= \frac{{(19.6)}^{2}}{2 \times 9.8} = 19.6 m$
