QUESTION 9
Block A, with a mass of 10 kg, rests on a 35° incline. The coefficient of static friction is 0.40. An attached string is parallel to the incline and passes over a massless,
frictionless pulley at the top. The largest mass of block B attached to the dangling end, for which A remains at rest is:
OA.5.9 kg
OB. 2.5 kg
OC. 10.5 kg
OD.9.0 kg
O E. 3.5 kg

![QUESTION 10
A father racing his son has 1/2 the kinetic energy of the son, who has 1/4 the mass of the father. The father speeds up by 1.7 m/s and then has the same kinetic energy
as the son. What are the original speeds of the father and the son, respectively?
OA. 1.4 m/s and 2.8 m/s
OB. 4.8 m/s and 10.2 m/s
OC.4.1 m/s and 11.6 m/s
OD.3.3 m/s 11.6 m/s
OE. 4.1 m/s and 8.3 m/s
QUESTION 11
The amount of work required to stop a moving object is equal to the:
O A. square of the velocity of the object
OB. kinetic energy of the object
OC. mass of the object times its acceleration
OD. velocity of the object
O E. mass of the object times its velocity
