A hockey puck is coming towards a hockey player at a velocity of 18 m/s [E]. The player hits the puck with her hockey stick, and the puck leaves her stick with a velocity of 11 m/s [W]. The puck was in contact with the stick for 0.4 s. What was the magnitude of the acceleration of the puck, in m/s2? Include at least 3 digits in your final answer. Hint: The magnitude of a vector quantity is simply the value without a direction. Note that the magnitude of a vector is always non- negative (either zero or positive). Answer: 17.5 x (72.5000000000)

A box rests on a surface (Fig. P6.64). A force Fapp is applied to the box in two different ways. In both cases. Fapp has the same magnitude, but in case 1 the force is directed below the horizontal, whereas in case 2 it is directed above the horizontal. a. Draw a free-body diagram for both cases. b. Now Fapp is increased in both cases until the box just barely remains at rest. Compare Fs, max for each free-body diagram. c. Use your answer to part (b) to find a best way to move a heavy desk. Describe and explain your solution.
The manager of a department store is pushing horizontally with a force of magnitude 200 N on a box of shirts. The box is sliding across the horizontal floor with a forward acceleration.

(c) Consider a tennis ball in contact with a stationary floor and with nothing else. Can the normal force be different in magnitude from the gravitational force exerted on the ball?

(a) Neglecting air resistance (a poor assumption, but we will make it for this example), calculate the shell’s velocity when it leaves the mortar. (b) The mortar itself is a tube 0.450 m long. Calculate the average acceleration of the shell in the tube as It goes from zero to the velocity found in (a). (c) What is the average force on the shell in the mortar? Express your answer in newtons and as a ratio to the weight of the shell.

(b) The block is resting on a surface tilted up at a 30.0 angle with respect to the horizontal. (c) The block is resting on the floor of an elevator that is accelerating upwards at 3.00 m./s2. (d) The block is on a level surface and a force of 125 N is exerted on it at an angle of 30.0 above the horizontal. (Sec Section 1.5.)
Figure P7.45 shows a picture of American astronaut Clay Anderson experiencing weightlessness on board the International Space Station. a. Most people have the misconception that a person in a spacecraft is weightless because he or she is no longer affected by gravity. Show that this premise cannot be true by computing the gravitational field of the Earth at an altitude of 200 km the typical altitude of a spacecraft in orbit. Compare this result with the gravitational field on the surface of the Earth. b. Why would astronauts in orbit experience weightlessness even if they are experiencing a gravitational field (and therefore a gravitational force)?
