Answer: 1.2m/s^2
Explanation: the force exerted on the car is 900N upwards
The mass of the car is 750kg
According to Newton's third law acceleration is proportional to force
F = ma
900 = 750a
a = 900/750
a = 1.2m/s^2
I think A but I dont really know
Force = mass × accelaration
Force = 0.25Kg × 196 m/s²
Force = 49 Newtons
