Question

A water skier has a mass of 86 kg and accelerates at 2 m/s2. What is the net force acting on him?

Ο Α.
0.0233 N
2
B.
43 N
C. 84N
D.
172 N

Answer 1

F = 172 N

Step-by-step explanation:

Newton's second law of motion gives the amount of force acting on an object. Mathematically, it is given by :

F=ma

Put m =86 kg and a = 2 m/s²

So,

`F=(86* 2)\ N\\\\F=172\ N`

Hence, the net force is 172 N.
