A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.50 x 10-³ s, and the force of the kick is given by F(t) = [(9.55 × 105)t - (6.37 × 108)t²] N for 0≤t≤1.50 x 10-³ s where t is in -3 I seconds. Find the magnitudes of the following: (a) the impulse on the ball due to the kick, (b) the average force on the ball from the player's foot during the period of contact, (c) the maximum force on the ball from the player's foot during the period of contact, and (d) the ball's speed immediately after it loses contact with the player's foot.

Two figure skaters are coasting in the same direction, with the leading skater moving at 5.5 m/s and the trailing skating moving at 6.2 m/s. When the trailing skater catches up with the leading skater, he picks her up without applying any horizontal forces on his skates. If the trailing skater is 50 heavier than the 50-kg leading skater, what is their speed after he picks her up?
A hockey puck of mass 150 g is sliding due east on a frictionless table with a speed of 10 m/s. Suddenly, a constant force of magnitude 5 N and direction due north is applied to the puck for 1.5 s. Find the north and east components of the momentum at the end of the 1.3-s interval.
Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
A block with mass m1 hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m2 that sits on a ledge slanted at an angle of 20 (Fig. P5.49). Suppose the system of blocks is initially motionless and held still, and then it is released. If m1 = 7.00 kg and m2 = 2.00 kg, find the magnitude of the acceleration of the blocks, assuming there is no friction between the second block and the ledge. FIGURE P5.49 Problems 49 and 50.
A space probe, initially at rest, undergoes an internal mechanical malfunction and breaks into three pieces. One piece of mass ml = 48.0 kg travels in the positive x-direction at 12.0 m/s, and a second piece of mass m2 = 62.0 kg travels in the xy-plane at an angle of 105 at 15.0 m/s. The third piece has mass m3 = 112 kg. (a) Sketch a diagram of the situation, labeling the different masses and their velocities, (b) Write the general expression for conservation of momentum in the x- and y-directions in terms of m1, m2, m3, v1, v2 and v3 and the sines and cosines of the angles, taking to be the unknown angle, (c) Calculate the final x-components of the momenta of m1 and m2. (d) Calculate the final y-components of the momenta of m1 and m2. (e) Substitute the known momentum components into the general equations of momentum for the x- and y-directions, along with the known mass m3. (f) Solve the two momentum equations for v3 cos and v3 sin , respectively, and use the identity cos2 + sin2 = 1 to obtain v3. (g) Divide the equation for v3 sin by that for v3 cos to obtain tan , then obtain the angle by taking the inverse tangent of both sides, (h) In general, would three such pieces necessarily have to move in the same plane?

A stone of mass m = 1.55 kg is dropped from a height of h = 3.9 m into a pool of water. At a time of t = 1.9 s after hitting the surface of the water, the stone's velocity has decreased by 50%. What is the magnitude of the average force the stone experiences, in newtons, during the time t?
A hockey player with a mass of M = 72 kg, standing on ice, pushes a plate with a mass of m = 0.5 kg in a horizontal direction at a speed of v = 30 m / s, which causes him to start moving in the opposite direction. After how long it stops if the coefficient of friction between the skates and the iceis kt = 0.02 and by how much does it move?
A baseball (m = 152 g) approaches a bat horizontally at a speed of 43.6 m/s (97.6 mi/h) and is hit straight back at a speed of 53.8 m/s (120 mi/h). If the ball is in contact with the bat for a time of 1.03 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
