Q. As part of a safety investigation, two 1200 kg cars travelling at 24 m/s are crashed into different barriers. Determine the average forces exerted on (a) the car that hits a line of water barrels and takes 1.5 seconds to stop, and (b) the car that hits a concrete barrier and takes 0.3 seconds to stop.
A sanding disk with rotational inertia 5.4 x 10-3 kg·m2 is linked to an electric drill whose motor delivers a torque of magnitude 10 N·m about the central axis of the disk. About that axis and with torque applied for 72 ms, what is the magnitude o..

A grinding wheel 0.45 in diam rotates at 2900. What is acceleration of a point on the edge of the grinding wheel.
Two balls of the same mass are accelerated by different net forces such that one ball gains a velocity twice that of the other ball in the process. Is the work done by the net force acting on the faster moving ball twice that done on the slower mo..
A 220 g block hangs from a spring with spring constant 12 N/m. At t=0;{rm s} the block is 31cm below the equilibrium point and moving upward with a speed of 89.0 cm/s. What is the block's distance from equilibrium while the speed is 30 cm/s.
A boy shoves his stuffed toy zebra down a frictionless chute, starting at a height of 1.67 m above the bottom of the chute and with an initial speed of 1.97 m/s. The toy animal emerges horizontally from the bottom of the chute and continues sliding a..
An intergalactic rock star bangs his drum every 1.70s. A person on earth measures that the time between beats is 2.5s. How fast is the rock star moving relative to earth.
Assume that we suddenly discovered that all these years we would be wrong about the distance from Earth to the Sun, and it is actually 10 percent greater than we would think. How would that affect our approximation of the distance to the Andromeda..
What is the direction of the object's acceleration after it is free. What is the magnitude of the objects acceleration.
What will the force be between these charges. What should the banking angle of the curves be so that the force of the pavement on the tires of the car is in the normal direction.
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
A hydrogen molecule with an initial velocity of 1200m / s makes a collision with a molecule of oxygen at rest. The reason for the masses of molecules is mO / mH = 16. What are the speeds of the molecules after collision.
