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

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 when the board hits the victim

To find: Force exerted on victim

The force is given by formula:

From given,

Substituting the values in formula,

Thus force exerted on victim is 20 newton

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

step-by-step explanation:

the true ones are a b and d
