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?
What is the length of the greatest and thinnest string that can be located under a tension of 860 without breaking .
explain the electric flux through the surface of the cube. Calculate the volume charge density of the atmosphere, assuming it to be uniform between 270 and 420 m.
A horse is capable of moving at four different speeds: walk (1.9 m/s), trot (5.0 m/s), canter (7.0 m/s), and gallop (12 m/s). Ann is learning how to ride a horse. She spends 15 minutes riding at a walk and 1.8 minutes at each other speed.
A particular Ferris wheel has a radius of 24 meters, and it makes one complete revolution around its axle (at location A) in 20 seconds. In all of the following questions, consider location A (at the center of the axle) as the location around whic..

How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
Find the position of an object in front of a screen to obtain an image of size twice larger than its original size on the screen.
What is the integral from s to p of B dot dL, where an integral is taken along the dotted path shown, first from point P to point R at (x,y) = (0.707d, 0.707d), and then to point S at (x,y) = (0.6d, 0.6d).
The dummy in a crash test has a head of mass 3 kg. The dummy is strapped in firmly so that the body does not move. The car's forward speed changes from 24 m/s to zero in 0.23 s.
The bowling ball has a diameter of 20.6 {rm cm}, and the angle the stick makes with the horizontal is 30.0 {rm ^circ}. You may suppose there is no friction between the stick and the bowling ball, though friction with the floor must be taken into acco..
