The ball hits a vertical wall and bounces off so that it is moving 63° above the horizontal, moving in the opposite direction with the same speed See the figure. Status re for What was the magnitude of the impulse delivered by the wall, am meters per second? R Status partial Completed Partial atano acotan Degrees Radians IEive up! Feedback: deductio Per feedback Hintsa for a 20. deduction Hints remaining L -Impulse is a vector quantity, so what is the change in in both the restical and horizontal How are you going to find the momentum in each direction?

Explanation / Answer

here vertical component remain unchanged and horizontal component reversed

J = mdv

J = 1.3 * (-11 -11)*cos63

J = -12.98 kg*m/s

magnitude = |J| = 12.98 kg*m/s
