Problem 14: Suppose a space probe of mass m1 = 4200 kg expels m, = 3300 kg of its mass at a constant rate with an exhaust speed of Vex = 2.15 x 10 m/s. art (a) What is the increase in speed, of the space probe, in terms of the variables given in the introduction? You may assume the is negligible at the probe's location. G De () mị – m2 Po Av = ver In Av = v In + vo Av = ver In + vo m1 - m2 m2 Su At (2 de m2 In m, Av = Vez In m1 - m2 Av = Ver Av = ver In m1 m1 m1 - m2 Submit Hint Feedback I give up! Part (b) Calculate the increase in speed, in meters per second, of the space probe.

2. A pitcher claims he can throw a baseball| with as much momentum as a 3.00-g bullet moving with a speed of 1 500 m/s. A baseball has a mass of 0.145 kg. What must be its speed if the pitcher's claim is valid?

Calculate the increase in velocity (in m/s) of a 4810 kg space probe that expels 3210 kg of its mass at an exhaust velocity of 4.00 ✕ 103 m/s. You may assume the gravitational force is negligible at the probe's location. The answer is 4400 m/s given by the homework website I tried using the conservation of momentum and the conservation of kinetic energy but did not get the right answer.

A Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 69.7 kg.( Figure 1) 2 masteringphysics.com/mycitemView?assignment ProblemID=189028758&offset=next W S Figure X command A # 3 20 E D C $ B 4 888 R F I % 5 of V 254 FD T G 6 B Part A 20 If Olaf catches the ball, with what speed ty do Olaf and the ball move afterward?
