Physics 101 Mechanics

A 2.0 kg solid sphere (radius = 0.15 m) is released from
rest at the top of a ramp and allowed to roll without slipping. The
ramp is 0.60 m high and 5.3 m long.
When the sphere reaches the bottom of the ramp, what is its
total kinetic energy?
Express your answer using two significant figures.
When the sphere reaches the bottom of the ramp, what is its
rotational kinetic energy?
Express your answer using two significant figures.
When the sphere reaches the bottom of the ramp, what is its
translational kinetic energy?
Express your answer using two significant figures.

A man with a mass of 67.8 kg stands on one foot. His femur has a cross-sectional area of 8.00 cm^2 and an uncompressed length of 51.3 cm. Young's modulus for compression of the human femur is 9.40 × 10^9 N/m^2.
How much shorter is the femur when the man stands on one foot?
What is the fractional length change of the femur when the person moves from standing on two feet to standing on one foot?
