You are driving 110 miles to Columbus from Cincinnati. The first 100 miles you drive a good speed of 75mi/h . Unfortunately, you hit a traffic jam the last 10 miles where at least you move a constant 8.00mi/h . Part A How long did it take you to make the trip to Columbus in hours? Part B What was your average speed for the trip in miles/h? Part C What was your average speed in m/s?
A 3.9 kg block originally at rest is pulled to the right along a horizontal, frictionless surface by a constant, horizontal force of 18 N.
A 71kg pole-vaulter falls from rest from a height of 4.6m onto a foam-rubber pad. The pole-vaulter comes to rest 0.4s after landing on the pad.
While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0 degree banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and the road to keep t..
How much heat does it take to enhance the temperature of 8.00 of an ideal monatomic gas from 22.0 to 61.0 if the gas is held at constant volume.
The force of repulsion that two like charges exert on each other is 4.0 N. What will the force be if the distance between the charges is increased to 6 times its original value.
Suppose that the air bubble is always in thermal equilibrium with the surrounding water.
Find out the normal force exerted on the crate by the elevator.
A 11 g bullet is fired horizontally into a 109 g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 142 N/m. The bullet becomes embedded in the block.
A 1260 kg is pulling a 335 kg trailer. Together the car and trailer have the acceleration of 2.15 m/s squared. Find out the net force on the car-trailer combination.
A bullet of mass 0.018kg traveling horizontally at a high speed of 290m/s embeds itself in a block of mass 4 kg that is sitting at rest on a nearly frictionless surface.
Two carts with masses of 12.5 kg and 4.5 kg, respectively, move in opposite directions on the frictionless horizontal track with speeds of 8 m/s and 5 m/s, respectively. The carts stick together after colliding head-on. Find the final speed of the..
The tallest volcano in the solar system is the 22km tall Martian volcano, Olympus Mons. An astronaut drops a ball off the rim of the crater and that the free fall acceleration of the ball remains constant throughout the ball's 22km fall at a value..
