Practice Problems for Illinois Learners
Problems
1.) A four kilogram
object is moving across a frictionless surface with a constant
velocity of 2 meters per second. Determine the force necessary
to maintain the state of motion.
2.) A net force of 10 Newtons acts on a box which has a mass of 2 kg. What will be the acceleration of the box?
3.) How much horizontal net force is required to accelerate a 1000 kg car at 2 m/s2?
4.) If an unbalanced force of 600 newtons acts on a body to accelerate it at +15 m/s2, what is the mass of the body?
5.) A body with a mass of 1 kg is accelerated by a force of 2 N. What is the velocity of this body after 5 s of motion?
2.) A net force of 10 Newtons acts on a box which has a mass of 2 kg. What will be the acceleration of the box?
3.) How much horizontal net force is required to accelerate a 1000 kg car at 2 m/s2?
4.) If an unbalanced force of 600 newtons acts on a body to accelerate it at +15 m/s2, what is the mass of the body?
5.) A body with a mass of 1 kg is accelerated by a force of 2 N. What is the velocity of this body after 5 s of motion?
Solutions
1.) 0, it's moving at a constant velocity.
2.) 5m/s^2
3.) 2000N
4.) F = ma
m=F/a
m = 600n/15 m/s2
m= 40 kg
5.) v = 10 m/s
2.) 5m/s^2
3.) 2000N
4.) F = ma
m=F/a
m = 600n/15 m/s2
m= 40 kg
5.) v = 10 m/s
