Question

5. An attacker swings a board with a mass of 2 kg toward a victim. The acceleration is 10 m/s2 when the board hits the victim. How much force did the board exert on the victim? Obj. 7.2​

Answer 1

The force exerted on victim is 20 newton

Solution:

An attacker swings a board with a mass of 2 kg toward a victim

The acceleration is 10 $m/s^2$ when the board hits the victim

To find: Force exerted on victim

The force is given by formula:

$F = mass \times acceleration$

From given,

$mass = 2 \text{ kg }\\\\Acceleration = 10$ $m/s^2$

Substituting the values in formula,

$Force = 2 \times 10 = 20$

Thus force exerted on victim is 20 newton
