Question

Skateboard falls with force of weight pulling downwards with 53 Newton’s accelerating at a rate of 9.81m/s what’s the mass of the skateboard

Answer 1

Point of correction, acceleration is 9.81 m/s2

Answer:

5.4 Kg

Explanation:

We know that F=ma and making m the subject of the formula then

$m=\frac {F}{a}$ where m is the mass of the skateboard, F is the pulling force and a is the acceleration of the body

Substituting 53 N for F and 9.81 m/s2 for a then

$m=\frac {53 N}{9.81 m/s2}=5.40265 Kg\approx 5.4 Kg$
