Question

How much force does a 6700kg cart have, accelerating at a rate of 84 m/s^2

Answer 1

According to Newton's second law, the force is equal to the product between the mass and the acceleration of the object:

`F=ma`
where m is the mass and a the acceleration.

For the cart in this problem, m=6700 kg and
`a=84 m/s^2`, therefore the force is

`F=ma=(6700 kg)(84 m/s^2)=5.63 \cdot 10^5 N`

Answer 2

From Newton's second law of motion,
Force = mass * acceleration, in short
F = ma

From the current scenario, m = 6700 kg and a = 84 m /s^2

Therefore,
Force, F = 6700*84 = 562800 N = 562.8 kN
