Question

ou launch a model rocket from ground level. It moves directly upward with a constant acceleration of 76.0 m/s2 for 1.25 seconds, at which point it runs out of fuel. Assuming air resistance on the rocket is negligible, what is the maximum altitude (above the ground) achieved by the rocket?

Answer 1

59.375 m

Step-by-step explanation:

This can be studied as a UAM (Uniformly Accelerated Motion). To find the maximum altitude we can use the following formula:

`y = v_(o)t + (at^(2) )/(2)`

We know that the rocket starts ar rest, so Vo = 0. So max altitude is calculated im the following way:

`y = 0 + (76x(1.25^(2))/(2) )`

`y = 59.37 m`
