1. A 2000kg car, initially at rest, is accelerated along a horizontal roadway at 3m/s^2. What is the average power required to bring the car to a final speed of 20m/s?
2. I don't know the relevant equations :(
3. Well I first tried force multiplied by the final velocity which is...
you can always use Vf^2=Vi^2+2ad
Vf would be 0 because it means that the motorcycle has stopped.
Vi would be the initial velocity.
a would be the acceleration.
Solve for d.
Btw the ACCELERATION due to gravity equals 9.81m/s^2.
So using the equation Vf^2 = Vi^2 + 2ad you can find the max height by solving for d.
Here's a clue: What is the final velocity at maximum height?

umm i set vf^2 = 0 so that it'll reach 150 as the max height and solved for theta and i got 10.37 as the angle. idk if that's correct, but now i have a starting point. thank you so much! :D
