Given information about the mass and the individual force values for an object, determine the acceleration. All accelerations are horizontal.
Mira and Tariq are lab partners for the Pulley and Bricks Lab. They have determined that the 2.74-kg brick is experiencing a forward tension force of 16.5 N and a friction force of 8.8 N as it is accelerated across the tabletop. Determine the …

Construct a free body diagram depicting the types of forces acting upon the brick.
After a lead-off single in the 8th inning, Earl makes an effort to steal second base. As he hits the dirt on his headfirst dive, his 68.4 kg body encounters 388 N of friction force. Construct a free body diagram depicting the types of forces acting upon Earl so that you can determine the magnitude of ...

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 69.3 N forward force on the wagon. There is a 31.3 N resistance force and the wagon and Casey have a combined weight of 316.0 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the acceleration of the wagon.
Ezra is occasionally asked to work the check-out line during his shifts at the Hy-Vee grocery store. During a recent lesson on Newton's Laws, he re-lived a memory from work. He wrote the following Physics problem and he wants you to solve it:
The handle of a paper grocery sack has a breaking strength of 321 N. Ezra loads the bag with 17.0-kg of soup cans. With what maximum acceleration can he lift the sack upward without breaking the handles?
Brandon is the catcher for the Varsity baseball team. He exerts a forward force on the 0.143-kg baseball to bring it to rest from a speed of 28.0 m/s. During the process, his hand recoils a distance of 0.112 m. Determine the ...
... acceleration of the ball.
... the force which is applied to the ball by Brandon.

Use a kinematic equation to determine the acceleration. Then use Newton's Laws to determine the force.
Leilani works in South's bookstore during Block 4. She applies a 58.5-N rightward force to a 8.03-kg crate filled with Titan-wear. The crate experiences a friction force of 41.2 N. Determine the acceleration.
A 1360.0-kg car is moving rightward at 23.6 m/s when it starts to skid to a stop. It encounters a force of friction of 11729 N. Determine the acceleration (in m/s/s) of the car.
