A hollow, spherical shell with mass 3.00 kg rolls without slipping down a 39.0 ∘ slope. Find the acceleration. Find the friction force

The acceleration is 5.66m/s²

The frictional force is 11.33N

Explanation:

Please see attached a rough sketch of the free body diagram for your reference

Given data

Mass m=3kg

Angle =39°

We know that the balancing force is given as

mgsinθ-f=ma

And the balancing torque is given as

FR=2/3mR²∝

Please see the attached for the annotated solution

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.  

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
