5. Rocket guidance A space probe with mass 5180 kg is traveling beyond Saturn with a velocity of 115 m/s. When it is time to alter its course by 30.0°, the probe's thruster jets are fired briefly in a direction perpendicular to its original motion. If the thruster gases are expelled at a speed of 1750 m/s, how much mass must be expelled during the course correction?
A space probe is traveling in outer space with a momentum that has a magnitude of 4.96 x 10 kg.m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.93 x 10 N and a direction opposite to the probe's motion. It fires for a period of 10.7 s. Determine the momentum of the probe after the retrorocket ceases to fire. A 48.0-kg skater is standing at rest...
A space probe with a rest mass of 8.0×10^7 kg and a speed of 0.51c smashes into an asteroid at rest and becomes embedded with it. **Part A: If the speed of the probe-asteroid system is 0.26c after the collision, what is the rest mass of the asteroid? Review Part A A space probe with a rest mass of 8.0x107 kg and a speed of 0.51c smashes into an asteroid at rest and becomes embedded within it If the speed...

A cruise ship with a mass if 1.53 x 10^7 kg strikes a pier at a speed of 0.652 m/s. It comes to rest 5.19 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) exerted on the pier using the concept of impulse. (Hint: first calculate the time it took to bring the ship to rest. Assume the ship moces in the positive direction. Indicate the direction with the sign of...
Question 1 10 pts 1) A mass of 4 kg is moving at some velocity and collides inelastically with a 7 kg moving in the-x direction at 10 m/s. After the collision, both masses are moving in the -x direction and the total kinetic energy of both masses is 68 Joules. What was the momentum of the 4 kg mass before collision in kg m/s? Include a negative sign if moving in the negativex direction.
Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm
i need just this question answered 7 Sho ..6.20 Screen 019-10 Sphere A, of mass 0.600 kg, is initially moving to the right at 4.00 m/s. Sphere B, of mass 1.80 kg, is initially to the right of sphere A and moving to the right at 2.00 m/s. After the two spheres collide, sphere B is moving at 3.00 m/s in the same direction as before. (a) What is the velocity (magnitude and direction) of sphere A after this collision?...
please help! The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
