Answer:
The amount of force needed is 36,400 N
Explanation:
In this question, we are asked to calculate the amount of force needed to reach a particular acceleration given the mass of the body.
Mathematically, the amount of force needed can be calculated using the mathematical equation below;
F = m * a
where m is the mass with a value of 9,100kg according to the question
and a is the acceleration with a value of 4 m/s^2
Plugging these values directly, we have ;
F = 9100 * 4 = 36,400N
