A solid sphere of mass 4.0 kg and radius 0.12 m starts from rest atthe top of a ramp inclined 15 degrees, and rolls to the bottom. Theupper end of the ramp is 1.2 m higher than the lower end. What isthe linear speed of the sphere when it reaches the bottom of theramp? (Note: I = 0.4 MR^2 for a solid sphere and g =9.8m/s^2)
a. 4.7m/s
b. 4.1 m/s
c. 3.4 m/s
d. 2.4m/s
