Answer:
10.5 kN
Explanation:
Force is a product of mass and acceleration, therefore, expressed as am=F
Where a is acceleration of an object, m is the mass and F is rhe force exerted.
Given m as 1400 kg and a as 7.5 m/s2 then force will be
F=1400*7.5=10500 N
Converted to kN
We know that 1 kN=1000 N
Therefore, to convert 10500 N to kN, we divide the above by 1000 hence 10500/1000=10.5 kN
Therefore, the force is equivalent to 10.5 kN
