A body is projected upwards with a velocity of 29.4 metre/second.

Calculate:-

1) the maximum height attained

2) the time taken to reach the maximum height.(g=9.8m/s)

Open in App

Solution

S=(v^2-u^2)/2a
s={0^2-(29.4)^2}/2*(-9.8)
s=44.1
I) 44.1m(ans)
v=u+at
t=(v-u)/a
t=-29.4/-9.8
t=3
2) 3m/s^2 (ans)
