Key chain angle a vehicle enters a circular and level highway exit ramp with a constant speed of v= 70 km/h. at this moment the driver notices that the ignition key chain makes an angle 0 with respect to the vertical. calculate this angle 0 if the radius of the ramp is r=50 m. 0=37.6°

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
