A 300 kg space probe in deep space has an initial velocity v =(12,–9,20) km/s. It fires its thrusts which exert a force of F =(247,0,–96)kN on the probe. (a) What is the angle between the force and momentum vectors? (b) Find the component of the force parallel to the probe's momentum vector. (c) Find the component of the force perpendicular to the probe's momentum vector. (d) Calculate the radius of curvature of the probe's path at this point.

Chapter 07, Problem 35 Your answer is partially correct. Try again. A projectile (mass target (with the projectile in it) flies off after being struck. What percentage of the projectile's incident kinetic energy does the target (with the projectile in it) carry off after being struck? 0.263 kg) is fired at and embeds itself in a target (mass = 2.14 kg).

What is the linear momentum of a 74.0 kg object on the Equator, as measured from the center of Earth? The radius R of Earth is 6371 km.

The carbon isotope 14C is used for carbon dating of archaeological artefacts. 14C decays to 14N by a process known as beta decay, in which the nucleus emits an electron (also known as a beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted in opposite directions to each other. The electron has a speed of 5 x 10 m/s and the neutrino has a momentum of 5 x 1024 kg m/s. n as What is the recoil speed of the resulting 14N nucleus? (Take the mass of the carbon-14 and nitrogen-14 nuclei to be 2.34 x 10 26 kg and the mass of the electron to be 9.11 x 1031 kg. If you were aware of such things and concerned, please ignore relativistic effects.)

An average-sized asteroid located 7.4 ✕ 107 km from Earth with mass 2.5 ✕ 1013 kg is detected headed directly toward Earth with speed of 8.0 km/s. What will its speed be (in km/s) just before it hits our atmosphere? (You may ignore the size of the asteroid. Assume the height of our atmosphere is 100 km.)

A rocket moving in space, far from all other objects, has a speed of 3.0 x 10* m/s relative to the Earth. Its engines are turned on, and fuel is ejected in a direction opposite the rocket's motion at a speed of 5.0 x 10* m/s relative to the rocket. (A) What is the speed of the rocket relative to the Earth once the rocket's mass is reduced to half its mass before ignition?

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 102 kg and the bag of tools has a mass of mp = 19.0 kg. If the astronaut is moving away from the space station at Vj = 2.10 m/s initially, what is the minimum final speed vp.f of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f = m/s
