Question

To estimate the maximum altitude reached by their rockets, the boys measured theO initial velocity of the rocketflight time of the rocketO internal diameter of the rocketO acceleration of gravity at the launch site

Answer 1

The maximum height of the rocket is determined as,

`h=(u^2\sin (\theta))/(2g)`

where u is the initial velocity, g is the acceleration due to gravity and

`\theta\text{ is the angle of the rocket initial velocity with the horizontal surface}`

As the value of acceleration due to gravity is constant, thus, the height reached by rocket can be changed with the magnitude or the direction of the initial velocity of the rocket.

Hence, the first option (initial velocity of the rocket flight time of rocket) is the correct answer.
