1. Two balls A and B of masses 100 grams and 300 grams respectively are pushed horizontally from a table of height 3 meters. Ball has is pushed so that its initial velocity is 10 m/s and ball B is pushed so that its initial velocity is 15 m/s. a) Find the time it takes each ball to hit the ground. b) What is the difference in the distance between the points of impact of the two balls on the ground?

ANSWER.
1. Two balls A and B of masses 100 grams and 300 grams respectively are pushed horizontally from a table
of height 3 meters. Ball has is pushed so that its initial velocity is 10 m/s and ball B is pushed so that its
initial velocity is 15 m/s.
a) Find the time it takes each ball to hit the ground.
b) What is the difference in the distance between the points of impact of the two balls on the ground?
2. A 250-lb block is initially at rest on a flat surface that is inclined at 30 degrees. If the coefficient of kinetic
friction is 0.30 and the coefficient of static friction is 0.40, find the force required to start the block moving
up the plane.
3. A rope of negligible mass is stretched horizontally between two supports that are 3.44 m apart. When an object
of weight 3160 N hung at the center of the rope, the rope is observed to sag by 35.0 cm. What is the tension in the
rope?
4. Two blocks of masses 5 kg and 7 kg are placed in contact with each other on a frictionless horizontal
surface. A constant horizontal force 20 N is applied to the block of mass 7 kg.
(a) Determine the magnitude of the acceleration of the two-block system.
(b) Determine the magnitude of the contact force between the two blocks.
