4. A 1-kg cannon ball is launched with an initial velocity of 40 m/s into a 20-m/s headwind. The aerodynamic drag force, in Newtons, acting on the cannon ball during its flight is Fɔ = -0.5v. The resulting acceleration, in m/s³, of the cannon ball due to this headwind and drag is a=-(10+0.5v, )i-(9.81+0.5v,)j where the components of velocity are in m/s. Determine the time of flight of the cannon ball.

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 vesc 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 ? = 2.67 × 106 g/m3 and volume V =1.71 × 1012 m3. Recall that the universal gravitational constant is G = 6.67 × 10-11 (Nm2)/(kg2).
An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 910 kgkg traveling initially at a speed of 53.0 km/hkm/h in a distance equal to the diameter of a dime, which is 1.8 cmcm? Express your answer in newtons.

The first known collision between space debris and a functioning satellite occurred in 1996: At an altitude of 700 km, a yearold French spy satellite was hit by a piece of an Ariane rocket.A stabilizing boom on the satellite was demolished, and the satellite was sent spinning out of control. Just before the collision and in kilometers per hour, what was the speed of the rocket piece relative to the satellite if both were in circular orbits and the collision was (a) head-on and (b) along perpendicular paths?
how would I solve this? A positive gas ion with mass 1.66×10^−27 kg is traveling with speed 150m/s in the +x-direction when it collides head-on with a negative gas ion with mass 2.32×10^−27 kg traveling with speed 150m/s in the −x-direction. The ions stick together. What is the total kinetic energy of the two-ion system immediately after the collision

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 rocket for use in deep space is to be capable of boosting a total load (payload plus rocket frame and engine) of 3.00 metric tons to a speed of 10 000 m/s. (a) It has an engine and fuel designed to produce an exhaust speed of 2 000 m/s. How much fuel plus oxidizer is required? (b) If a different fuel and engine design could give an exhaust speed of 5 000 m/s, what amount of fuel and oxidizer would be required for the same task? (c) Noting that the exhaust speed in part (b) is 2.50 times higher than that in part (a), explain why the required fuel mass is not simply smaller by a factor of 2.50.
