A person holds a ball in her hand. (a) Identify all the external forces acting on the ball and the Newtons third-law reaction force to each one. (b) If the ball is dropped, what force is exerted on it while it is falling? Identify the reaction force in this case. (Ignore air resistance.)
For all three situations, find the magnitude and direction of the tension force(s) exerted on Rochelle. If not enough information is given, say so. Explain your answers. a. Rochelle and Buddy pull on opposite ends of rope. The tension force exerted on Buddy is 15 N and is directed toward Rochelle. b. Now, one end of the rope is tied to a sturdy pole and Rochelle pulls on the other end. The tension force on the pole is 15 N directed toward Rochelle. c. Finally, Rochelle holds one rope in her left hand, and the other end of that rope is pulled by Joe. She holds another rope in her right hand, and the other end of that rope is pulled by Buddy. Both Buddy and Joe experience a 15-N force directed toward Rochelle.
In Figure P1.84, the pulleys and the cord are light, all surfaces are frictionless, and the cord does not stretch. (a) How does the acceleration of block 1 compare with the acceleration of block 2?

When you learn to drive, you discover that you need to let up slightly on the brake pedal as you come to a stop or the car will stop with a jerk. Explain this in terms of the relationship between static and kinetic friction.
A car is moving forward slowly and is speeding up. A student claims that the car exerts a force on itself or that the cars engine exerts a force on the car. (a) Argue that this idea cannot be accurate and that friction exerted by the road is the propulsive force on the car. Make your evidence and reasoning as persuasive as possible. (b) Is it static or kinetic friction? Suggestions: Consider a road covered with light gravel. Consider a sharp print of the tire tread on an asphalt road, obtained by coating the tread with dust.
Three blocks, light connecting ropes, and a light frictionless pulley comprise a system, as shown in the figure. An external force of magnitude P is applied downward on block A, causing block A to accelerate downward at a constant 2.5 m/s2. The tension in the rope connecting block B and block C is equal to 60 N. What is the magnitude of the force P? What is the mass of block C? Please include detailed answers with net force equations.
Hi there, I need some help on drawing this free body diagram for this scenario. I do know that normal force, weight, drag, and kinetic friction forces are the ones that are acting in this scenario. I just can't seem to get the diagram drawn correctly, supposing the car is moving to the right. Scenario: Your car is skidding to a stop from a high speed. Thank you!
(Background Info) A car has a mass of 1600 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 8000 N. Draw all diagrams by hand. (Question) Draw a picture and identify all the forces acting on the car while the brakes are applied before it stops. Draw a free body diagram (FBD) of the car during this time. Don’t forget to label your coordinate system. Additionally, if the car was initially moving at 20 m/s, what is the shortest distance in which the car can stop safely?
