An 20.g bullet is fired from a rifle having a barrel 0.50 m long. Choosing the origin to be at the location where the bullet begins to move, then the force (in newtons) exerted by the expanding gas on the bullet is given by: F(x) = 1.7.10^3N + (1.0.10^2 N/m) x - (2.610^3 N/m^2)x^2 where x is in meters. Find the speed of the bullet as it leaves the barrel.

A satellite is floating in space. Solar wind sweeping past the satellite consists of a stream of particles, mainly hydrogen ions of mass 1.7×10−27 kg. There are about 0.5×105 ions per cubic meter, and their speed is 8.0×105 m/s. An `umbrella' attached to the satellite is slowly opened, such that the radius of the circular cross-section of the umbrella is changing with time as r(t)=bt2, where b=0.1 m/s2 is a constant (see the figure which shows the side and front views). What is the maximum change of momentum of the satellite due to the solar wind hitting this umbrella after a time of 10 seconds? Explain carefully why this is the maximum possible change. You must explain your reasoning every step of the way!
A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed ?esc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density ?=2.93×106 g/m3 and volume ?=1.94×1012 m3 . Recall that the universal gravitational constant is ?=6.67×10-11 N·m2/kg2 .vesc = ? m/s

A particle P of mass m = 0.56 kg is released from rest at a point h = 7 m above the surface of a liquid in a container. P falls through the air into the liquid. Assume there is no air resistance and there is no instantaneous change in speed of P as it enters the liquid. When P is at a distance of d = 0.71 m below the surface of the liquid, P's speed is v = 4.9 m/s. The only force acting on P due to the liquid is a constant resistance to motion of magnitude R N. Find the following: v1: The speed (in m/s) of P the moment just before it strikes the surface of the fluid.a1: The magnitude of the deceleration (in m/s2) of P while it is falling through the liquid.R: The magnitude of the resistance force (in N). The depth of the liquid in the container is dp = 3.9 m. P is taken from the container and attached to one end of a light inextensible string. P is placed at the bottom of the container and then pulled vertical upwards with a constant acceleration, a2. The resistance force to motion R N…

In a research facility, a person lies on a horizontal platform which floats on a film of air. When the person's heart beats, it pushes a mass m of blood into the aorta with speed v, and the body and platform move in the opposite direction with speed V. Assume that the blood's speed is 56.5 cm/s. The mass of the person + platform is 54.0 kg. The platform moves 5.95 ✕ 10−5 m in 0.160 s after one heartbeat. Calculate the mass (in g) of blood that leaves the heart. Assume that the mass of blood is negligible compared with the total mass of the person, and the person + platform is initially at rest. (Also assume that the changes in velocity are instantaneous.)
