3a A 0.2 kg mass is attached to a spring that is compressed against a heavy brick. The mass begins at the originof a coordinate system as shown (Note that +y is pointing down). At t = 0s, the spring is released and the massand brick are allowed to fall. The mass accelerates at 3.2 m/s² due to the spring and 9.8 m/s² due to gravity.+x+yWhat is the displacement vector of the mass after 2.5 s?

A baseball is thrown vertically upward. The mass of the baseball is m, and its initial speed is vi. a. What is the momentum of the baseball at its maximum height? b. What is the momentum of the baseball when it has traveled three-fourths of the total distance in its up-and-down motion?
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? Why?

Your mass is 67.6 kg, and the sled s mass is 14.4 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 4.49 m/s. What will be your speed on the ice after jumping off?
During a car collision, the knee, thighbone, and hip can sustain a force no greater than 4000 NN. Forces that exceed this amount could cause dislocations or fractures. Assume that in a collision a knee stops when it hits the car's dashboard. Also assume that the mass of the body parts stopped by the knee is about 20% of the total body mass. The person with a mass of 90 kgkg is initially traveling at 18 m/sm/s (40 mi/hmi/h). What minimum stopping time interval in needed to avoid injury to the knee? What is the minimum stopping distance?
