Homework Statement 1. A bottle rocket has an engine that accelerates it upward. Then it coasts to its highest point before returning to the ground. Assuming that the engine creates a net acceleration of 30 m/s2 for 0.5 s, how high does it go, and how long does it take to reach the ground...

how exactly do i get there again?

I know they net acceleration is 30m/s^2 and the time is 0.5s my thing is how do we calculate distance with only acceleration and time ?

I got 26m and it was correct! thank you so much! :)

the Second question is what i am confused on

A car is traveling at a steady 74 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 8.0 m/s2 . How much time elapses before the motorcycle is moving as fast as the car? How far is the motorcycle from the car when it reaches this...

Homework Statement acceleration =8.0m/s constant= 74km/h displacement 50 km/h? Homework Equations How much time elapses before the motorcycle is moving as fast as the car? How far is the motorcycle from the car when it reaches this speed? The Attempt at a Solution Is there a formula where i...

My name is Mary and i am taking physics this summer to try to get ahead. I am not the best at physics so I was hoping I would be able to get a little guidance while doing my homework problems.
