To lift off from the Moon, a 9.50 105 kg rocket needs a thrust larger than the force of gravity. If the exhaust velocity is 4.25 103 m/s, at what rate does the exhaust need to be expelled to provide sufficient thrust? The acceleration due to gravity on the Moon is 1.62 m/s2.
There is a compressed spring between two laboratory carts of masses m1 = 105 g and m2 = 212 g. Initially, the carts are held at rest on a horizontal track (Fig. P10.40A). The carts are released, and the cart of mass m1 has velocity vi=2.035i m/s in the positive x direction (Fig. 10.40B). Assume rolling friction is negligible. a. What is the net external force on the two-cart system? b. Find the velocity of cart 2. FIGURE P10.40 Problems 40 and 41.
A rocket has total mass Mi = 360 kg, including Mfuel = 330 kg of fuel and oxidizer. In interstellar space, it starts from rest at the position x = 0, turns on its engine at time t = 0, and puts out exhaust with relative speed ve = 1 500 m/s at the constant rate k = 2.50 kg/s. The fuel will last for a burn time of Tb = Mfuel/k = 330 kg/(2.5 kg/s) = 132 s. (a) Show that during the burn the velocity of the rocket as a function of time is given by v(t)=veln(1ktMi) (b) Make a graph of the velocity of the rocket as a function of time for times running from 0 to 132 s.

A toy rocket with a mass of 300 g takes off in an upward vertical direction under the influence of thrust and gravity. It burns fuel at the rate of 25 g/s. The exhaust speed of the gas is 80 m/s. What is the speed of the rocket at the end of 10 seconds? (g = 9.8 m/s²)
Kaya, a crew member on an interplanetary space ship, is on a spacewalk. She realizes that her ship is moving away from her at 0.5 m/s. She and her spacesuit have a total mass of 95 kg. Her space suit includes a 15 kg backpack, which is included in the 95 kg total mass.a). What is the minimum velocity she will have to throw the backpack so that she can gain enough velocity to eventually catch up with the ship? b). Kaya applies an average force of 400 N to the backpack for 0.05 seconds. Will Kaya make it back to the ship? If so, determine how much time it will take for her to reach the ship. If not, determine how much more force she would need to apply to make it back.
