I agree with Durro. Except I would like to clarify one point. In order to calculate the force we need to know the mass of the object (in this case 70 kg) and the acceleration (m/s^2) <In this case, we will use 3 miles per hour which = 1.34 m/s^2> Multiply the numbers for mass and acceleration to find the force of the object. 70 kg * 1.34 m/s^2 = 187.60 N ..... "creates enough force to cause severe injury."
