Q. A 0.5 kg block of ice is sliding by you on a very slippery floor at 2.5m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.0025 seconds. The block eventually slides at an angle of 22 degrees from its original direction. The overhead view is approximately to scale. The arrow represents the average force your toe applies briefly to the block of ice.
1. What is the unit vector in the direction of the block's momentum after kick?
2. What is the x-component of the block's momentum after kick?
3. What is the magnitude of the block's momentum after kick?
4. Make use of your answers to the preceding questions to find the z-component of the block's momentum after the kick.
5. What was the magnitude of the average force you applied to the block?
A 0.14 kg ball is placed in a shallow wedge with an opening angle of 126°. For each contact point between the wedge and the ball, determine the force exerted on the ball. Assume the system is frictionless.

Question on constant speed
At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accele..

A worker stands still on a roof sloped at an angle of 21° above the horizontal. He is prevented from slipping by a static frictional force of 400 N. Find out the mass of the worker.
An unmarked police car, travelling a constant 94 km/h, is passed by the speeder travelling 153 km/h. precisely 0.70 s after the speeder passes, policeman steps on the accelerator. If the police car's acceleration is 2.30 m/s^2, how much time elapses ..

The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. Suppose that only static friction supplies the centripetal force, & find the radius r of the tyre.
A 6 kg block slides along a frictionless horizontal surface. The block is acted on by two forces, a 4.5 N force to the left, and a 7.5 N force to the right. At what rate is the 4.5 N force doing work on the block at the instant when its speed is 4..
