Blaine steps onto a ski slope with an angle of 25°. There is a coefficient of kinetic friction of 0.15 between him and the groun
d. He has a mass of 65 kg.
Draw the free-body diagram showing the forces acting on Blaine.
Draw the free-body diagram showing the forces acting on Blaine.
1 answer:
θ = angle of the incline surface from the horizontal surface = 25⁰
μ = Coefficient of friction = 0.15
m = mass of the person = 65 kg
= kinetic frictional force acting on the person as he slides down
mg = weight of the person acting in down direction
= normal force by the incline surface on the person
the free body diagram showing the forces acting on the person is given as

Answer:
t=7.33 s
Explanation:
According to Newton's second law:
because we don't want the box to slide, the acceleration has to be zero.
we know that:
Now having the acceleration, we can use the following formula.
