A 50 kg student stands on a 4 kg skateboard at rest. The student catches a 9 kg backpack moving with a horizontal speed of 2
m/s in the direction the skateboard is free to roll.
How fast will the student and the skateboard move after catching the backpack, assuming friction is negligible? Round your
final answer to the hundredths place (two decimal places) (no zero before the decimal)
