a 43.7 kg student runs down the sidewalk and jumps with a horizontal speed of 4.48 m/s onto a stationary skateboard. the student and the skateboard move down the sidewalk with a speed of 4.25m/s. find the mass of the skateboard in units of kg. how fast would the student have to jump to have a final speed of 6.94 m/s?
