A force of 4.0 N is exerted on a 8.0 g rifle bullet. What is the bullet's acceleration? Your Answer: Answer

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .   The force of the impact is newtons.

Question 16 In experiment 101, the hover puck has a mass of 1000g, photogate 1 is at the 20-cm mark, photogate 2 is at the 70-cm mark, and the hanging weight is 100 g. What is the accepted value of the acceleration of the hover puck? Use g- 980 cm/s2. O 0.49 m/s2 O 0.69 m/s? O 0.89 m/s? O 0.29 m/s2

The maximum force that can be put on an egg without breaking it has been determined to be 15 N.  If the 0.15 kg egg is moving at 10.0 m/s and needs to be brought to a stop.  How much time will need to be allowed for it to slow down?

Question 6 6. The masses of the Atwood's machine are M 8.657 kg and m 2.616 kg. The acceleration (m/s2) of the system is:

Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive.  This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg.  The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero).   Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

ou are pushing your friend in his wheelchair. You are both taking his dog, Wrathbone, to the vet. Wrathbone is 5 kg and is sitting in your friend’s lap. You decide to increase the wheelchair’s acceleration to 7 ms2 in order to get up a steep ramp. If your friend has a mass of 46 kg and his wheelchair has a mass of 16 kg. What is the force you are applying?

A lamp hangs vertically from a cord in a descending elevator that decelerates at 1.7 m/s2. (a) If the tension in the cord is 63 N, what is the lamp's mass? (b) What is the cord's tension when the elevator ascends with an upward acceleration of 1.7 m/s2?

A person catches a ball with a mass of 145 g dropped from a height of 60.0 m above his glove. His hand stops the ball in 0.0100 s. What is the force exerted by his glove on the ball? Assume the ball slows down with constant acceleration.
