... 18. [C] There are a few ways to do this problem. The way I would do it is using conservation of energy: mgh + 0.5mv0²=0.5mvf², solving for h: h=[(0.5vf²0.5v0²)/(g)]=[(0.5(92)²-0.5(45)²)/9.8]=330 m You can use projectile motion equations, also. We can find the y component if velocity and solve for th ...

... An inertial reference frame is one in which Newton’s first law is valid.This excludes rotating and accelerating frames. An example is a cup resting on the dashboard of a car. It will stay at rest as long as the car’s velocity remained constant. If the car is accelerating, the cup may begin to move t ...
