Use the Newton's second law equation and an understanding of force diagrams and net force to solve the following problems.
Leilani works in South's bookstore during Block 4. She applies a 130.0-N rightward force to a 20.0-kg crate filled with Titan-wear. The crate experiences a friction force of 60.0 N.
Determine the net force exerted upon the crate.
Net Force =
N
Determine the acceleration.
Acceleration =
m/s2
It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year-old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 100.0 N forward force on the wagon. There is a 30.0 N resistance force and the wagon and Casey have a combined mass of 50.0 kg. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force and acceleration of Casey and the wagon.
Determine the net force experienced by Casey and the wagon.
Determine the acceleration of Casey and the wagon.
Darrel Deval, a 80.0-kg skydiver, is experiencing 200 Newton of air resistance.
Determine the net force experienced by Darrel. (Magnitude only; no + or -.)
Determine Darrel's acceleration. (Magnitude only; no + or -.)
What is the direction of Darrel's acceleration?
