(1) The parallel force on the Jumper is 441.42 N.

(2) The weight of the person is heavier on Earth when compared to Mars by 610 N.

Parallel force on the Jumper

The parallel force on the Jumper is determined from the parallel components of the weight of the jumper.

F = W x sinθ

F = (85 x 9.8) x sin32

F = 441.42 N

Weight of the person on Earth

W = mg

W = 100 x 9.8

W = 980 N

Weight of the person on Mars

W = mg

W = 100 x 3.7

W = 370 N

Difference between the weights

= 980 N - 370 N

= 610 N

Thus, the weight of the person is heavier on Earth when compared to Mars by 610 N.
