Question 3(adsbygoogle = window.adsbygoogle || []).push({});

A toy rocket is fired vertically upwards with an initial velocity of 29.2 ms-1. Calculate how long (in s) the rocket stays in the air before it returns to the ground.

s=?

u=29.2

v=0

a=-g

t=?

i've used t=(v-u)/a and then multiplied the answer by 2

is this the correct method to calculate the answer.

thanks in advance
