Consider a uniform solid sphere of radius r and mass m rolling without slipping. the moment of inertia of the sphere about an axis through its center is 25mr2. which form of its kinetic energy is larger, translational or rotational? consider

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Suppose astronomers built a 140-meter telescope. how much greater would its light-collecting area be than that of the 10-meter keck telescope? express your answer using two sign
