A small asteroid (mass of 150 g ) strikes a glancing blow at a satellite in empty space. The satellite was initially at rest and the asteroid was traveling at 2500 m/s . The satellite's mass is 140 kg . The asteroid is deflected 10 ∘ from its original direction and its speed decreases to 1200 m/s , but neither object loses mass. a.Determine the direction and of the satellite after the collision. Assume the initial direction of the asteroid...

Problem 1 An object of mass m1 travels through empty space at a constant speed until it strikes and sticks to a second object. As observed from the frame where the second object is motionless, the first object was traveling at a speed of vi. In that same frame, both objects travel at a speed of v after the collision. a. What is the general expression for the mass of the second object in terms of mi, vi, and v?...

An astronaut of mass 60 kg is on a space walk to repair a communications satellite when he realizes he needs to consult the repair manual. You happen to have it with you, so you throw it to him with a speed 4 m/s relative to the spacecraft. He is at rest relative to the spacecraft before catching the 3 kg book. Find (a) his velocity after catching the book (b) the initial and final kinetic energies of the book-astronaut...

A 2.1 kg firecracker is initially flying upwards in a vacuum space with no gravity with a speed 2 of 5.0 m/s. The firecracker is then exploded into 3 fragments, which all have one-third of the original unexploded mass. As shown in the figure, the 1st fragment is flying with a speed of 7.0 m/s and a 35° angle below a horizon, and the 2nd piece is flying upwards with 12 m/s. [4 pts] Find the final speed v3 and...

3.) A jet plane is flying with a constant speed along a straight line at an angle of 30° above the horizontal. The plane has a weight W of magnitude 86500 N and its engines provide a forward thrust T of magnitude 103000 N. In addition, the lift force L (directed upwards perpendicular to the wings) and the force R of air resistance (directed opposite the motion) act on the plane. Find L and R. [L = 74900 N; R=...
