1. A 15.0 kg object is thrown vertically into the air. [f the initial acceleration of the object is 8.80 m/s, whut is the applied force? 2. An object is pulled west along a horizontal frictionless surface with a steady horizontal force of 12.0 N. If the object accelerates from rest to a velocity of 4.0 m/s while moving 5.0 m, what is the mass of the object? 3. A horizontal force of 90.0 N is roquired to push a 75.0 kg object along a horizontal surface at a constant speed. What is the force of friction? 4. Two masses of 1.5 kg and 2.0 kg are hung on a frictionless pulley, as shown in the diagram. What is the acceleration of: a) the 1.5 kg mass? 1.5 kg 2.0 kg b) the 2.0 kg mass? 5. An 8.0 kg object is pulled vertically upward by a rope. If the tension in the rope is constant at 95 N, what is the velocity of the onject after I.1 s? (Assume the ohjec: was initial y at rest.)

Newton's Laws and Friction
1. A 15.0 kg object is thrown vertically into the air. If the initial acceleration of the object is 8.80 m/s',
wlut is the applied force?
2. An object is pulled west along a horizontal frictionless surface with a stcady horizontal force of
12.0 N. If the object accelerates from rest to a velocity of 4.0 m/s while moving 5.0 m, what is the
mass of the object?
3. A horizontal force of 90.0 N is roquired to push a 75.0 kg object along a horizontal surface at a
constant speed. What is the force of friction?
4. Two masses of I.5 kg and 2.0 kg are hung on a frictionless pulley, as showe in
the diagram. What is the acceleration of:
a) the 1.5 kg mass?
1.5 kg
2.0 kg
b) the 2.0 kg mass?
5. An 8.0 kg object is pulled vertically upward by a rope. Ithe tension in the rope is constant at 95 N,
what is the velocity of the onject after 1.1 s? (Assume the ohject was initial y at rest.)
6. Two blocks are tied tagether with a string. Ifa force
of 20.0 N is applied w the 2.0 kg block, as shown in
the diagram,
3.0 kg
20kg FT
