A water skier has a mass of 86 kg and accelerates at [tex]2 \, \text{m/s}^2[/tex]. What is the net force acting on him?

A. 0.0233 N
B. 43 N
C. 84 N
D. 172 N

Answer :

Answer:

F = 172 N

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,

[tex]F=(86\times 2)\ N\\\\F=172\ N[/tex]

Hence, the net force is 172 N.
