An acrobatic airplane performs a loop at an airshow. The centripetal acceleration the plane experiences is 14. 7 m/s2. If it takes the pilot 45. 0 seconds to complete the loop, what is the radius of the loop? round your answer to the nearest whole number.

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?
