# Honors Review Problems

Honors Review Problems Determine the current in the battery in each circuit A) B)

Use the graph to answer the following questions Determine the acceleration of the object for the first 4 seconds, 4s 6s, 6s 8s, and 8s 10s Determine the total displacement for all 10 seconds. Determine the distance traveled in all 10 seconds A marble is launched at 20.0m/s

A) horizontally from a height of 2.50m. 1) Determine its range. 2) Determine its impact velocity B) at an angle of 60 above horizontal. 1) How far from the launch position does it land? (assume a level surface) 2) What is the marbles maximum height? 3) What is the marbles speed at the zenith?

Newtons Laws Problems Determine the net force to A) make a 1300kg car reach a speed of 30m/s in 5.50 seconds from a standing start. B) raise a 25kg mass 1.50m straight upward at a CONSTANT speed. Determine the applied force to A) get a 10kg block to start sliding on a level surface with mk = 0.45 and ms = 0.55

B) keep the 10kg block to sliding at a constant velocity across the same level surface Newtons First Law Review For the following situations, determine if there IS or ISNT a NET force: A penny has JUST been released from the hand of a mischievous youth leaning over the edge of the observation deck of the Empire State Building The penny has fallen for long enough that it is at terminal velocity A person rides a Ferris wheel that goes round at a constant speed. A bicyclist pedals hard to maintain a constant speed while riding up an

inclined road A satellite orbits the earth at a constant speed in a perfect circle A ball tossed straight upward stops momentarily at the zenith of its path UCM Determine: The net force on a 25.0g stopper that completes 10 circles around a circle with a radius of 0.90m in 3.5 seconds The normal force on a 75kg passenger of a 5.0m radius Ferris wheel that

completes ten rotations in 63.5 seconds When they are at the TOP When they are at the BOTTOM W&E A 2000 kg roller coaster car is raised at a constant speed up a 40.0m tall hill in 3.0 minutes Determine the work done, and power required Neglecting friction and drag, how fast will the roller coaster be going when it reaches ground level, if it was rolling at 2.5m/s when it

started its descent? How far would it take to stop a 1500kg car to stop from 30m/s using a 13 000N friction force?
