The skateboard is initially at rest. Ignore frictions and gravity. Draw a picture. Part C Find the total kinetic energy of the skateboard plus student after the student hopped on the skateboard, O 891 J O 767 J O 1750 J 1110 J O 2420 J Submit Request Answer Part D Ten seconds after the student hopped on the skateboard, the student was observed by an observer standing next to the road, to have jumped off the skateboard in the +x direction with a speed that is much faster than the speed before the jumped off. Draw a picture. Right after the jumped off, the change in the magnitude of the total linear momentum of both the skateboard and student is? positive
