A missile of mass 1.05 102 kg is fired from a plane of mass 4.60 103 kg initially moving at a speed of 2.95 102 m/s. If the speed of the missile relative to the plane is 1.16 103 m/s, what is the final velocity of the plane?
Homework Answers
by conservation of momentum
initial momentum = final momentum
let the final velocity of plane be v then,
(1.05 * 10^2 + 4.6 * 10^3) * 2.95 * 10^2 = 1.05 * 10^2 * (v + 1.16 * 10^3) + 4.6 * 10^3 * v
v = 269.113 m/s
final velocity of plane = 269.113 m/s

A car with mass MC = 1.26 x 103 kg runs into the back of a truck with mass MT = 3.23 x 103 kg that is initially at rest. Immediately after the collision, the car is moving with a speed of 1.09 m/s and the truck is moving with a speed of 3.29 m/s, both in the direction the car was initially traveling. What is the total kinetic energy lost in the collision? (Of course, the change in energy...
