A 62 kg wake boarder is being pulled by a boat with a force of 124 N. What is the acceleration of the wake boarder?

Answers

Answer: 2m/s

Explanation:

The acceleration of the wake boarder is equal to 2 m/s².

What is acceleration?

Acceleration of a body can be described as the change in velocity of a body with respect to time. The acceleration is a vector parameter posses both magnitude and direction. Acceleration is described as as the second derivative of position w.r.t. time and the first derivative of the velocity of an object w.r.t. time.

According to Newton's 2nd law of motion, the force (F) acting is equal to the product of the mass and acceleration (a).

F = ma

or,   a = F/m

Therefore, acceleration (a) is inversely proportional to the mass (m).

Given, the force with which the boat pulled wake boarder, F = 124 N

The mass of the wake boarder = 62 Kg

The acceleration of the wake boarder, a = 124/62 = 2 m/s²

Therefore, the acceleration of the wake boarder is 2 m/s².
