Answer:
Coefficient of static friction will be equal to 0.642
Explanation:
We have given acceleration
Acceleration due to gravity
We have to find the coefficient of static friction between truck and a cabinet will
We know that acceleration is equal to , here
is coefficient of static friction and g is acceleration due to gravity
So
So coefficient of static friction will be equal to 0.642
(a) 328.6 kg m/s
The linear impulse experienced by the passenger in the car is equal to the change in momentum of the passenger:
where
m = 62.0 kg is the mass of the passenger
is the change in velocity of the car (and the passenger), which is
So, the linear impulse experienced by the passenger is
(b) 404.7 N
The linear impulse experienced by the passenger is also equal to the product between the average force and the time interval:
where in this case
is the linear impulse
is the time during which the force is applied
Solving the equation for F, we find the magnitude of the average force experienced by the passenger:
