Q1.A 10 kilogram mass rests on a horizontal frictionless surface. A
horizontal force of 5 Newtons is applied to the mass. After the force has been applied for 1
second, the velocity of the mass is:

1) 0 meters per second
2) 0.5 meters per second
3) 5 meters per second
4) 50 meters per second
ANSWER: 2 -- 0.5 METERS PER SECOND

Q2; Multiple Choice: A worker lifts a 10 kilogram block a vertical height of 2 meters. The
work he does on the block is:

1) 5 Joules
2) 20 Joules
3) 49 Joules
4) 200 Joules
ANSWER: 4 -- 200 JOULES

Q3; Multiple Choice: An impulse of 10 kilogram-meter per second acting on an object
whose mass is 5 kilogram will cause a change in the objects velocity of:

1) 0.5 meters per second
2) 2 meters per second
3) 10 meters per second
4) 50 meters per second

ANSWER: 2 -- 2 METERS PER SECOND
Q5; Multiple Choice: The time needed for a net force of 10 newtons to change the velocity
