Answer:
Part a)
Part b)
force is 21.2 times more than the weight of the person
Explanation:
Part a)
As it is given that the distance after which he stopped is given as
d = 1.50 cm
here finally it stops so final speed is given as
initial speed is given as
now by the equation of kinematics we know that
Now the force on the leg is given as
m = mass of leg = 13 kg
Part b)
Force due to weight of the object
here we know
M = 75.0 kg
Now we know that the ratio of the weight with the force on leg is given as
so force is 21.2 times more than the weight of the person
