A solid sphere of mass 4.0 kg and radius 0.12 m starts from rest at the top of a ramp inclined 15, and rolls to the bottom. The upper end of the ramp is 1.2 m higher than the lower end. What is the linear speed of the sphere when it reaches the bottom of the ramp? (Note: I = 0.4MR2 for a solid sphere and g = 9.8 m/s2)

Here is the answer for the question – A solid sphere of mass 4.0 kg and radius 0.12 m starts from rest at the top of a ramp inclined 15, and rolls to the bottom. The upper end of the ramp is 1.2 m higher than the lower end. What is the linear speed of the sphere when it reaches the bottom of the ramp? (Note: I = 0.4MR2 for a solid sphere and g = 9.8 m/s2). You’ll find the correct answer below

What is the linear speed of the sphere when it reaches the bottom of the ramp? (Note: I = 0.4MR2 for a solid sphere and g = 9.8 m/s2)

The Correct Answer is

4.1 m/s

Reason Explained

4.1 m/s is correct for A solid sphere of mass 4.0 kg and radius 0.12 m starts from rest at the top of a ramp inclined 15, and rolls to the bottom. The upper end of the ramp is 1.2 m higher than the lower end. What is the linear speed of the sphere when it reaches the bottom of the ramp? (Note: I = 0.4MR2 for a solid sphere and g = 9.8 m/s2)
