1. A bullet leaves a 24 inch rifle barrel at 900 ft/s. What was its acceleration and time in the barrel? 2. A train has an initial velocity of 54 mph. 4 minutes later it slows to a stop at an intersection. What is the acceleration? How far did it travel before coming to a stop?
A wheel undergoes 80 rev as it slows from 17 mph to 11 mph over the distance of 2.0 m a) What rotational acceleration does the wheel undergo? b) At this acceleration, how long would it take for the wheel to come to a complete stop?
A train is moving along a straight track with an initial velocity of 8 m/s when it is subjected to a deceleration of a-1.6/v m/s2, where v is in m/s. 2. How far does the train travel before it stops? How much time does it take to stop? a. b.
A train on a straight track starts from rest t station A. It accelerates for 20 seconds with an acceleration of 5 m/s^2 and then continues to travel at the velocity reached for two minutes. The train then decelerates at 5 m/s^2 for 20 seconds before coming to a stop at the next station B. What is the distance between the two stations?
1. A bicycle slows down uniformly from an initial velocity vi = 8.70 m/s to rest over a distance of 125 m. Each wheel has an overall diameter of 690 cm. You can assume that the wheels roll without slipping. (a) Calculate the angular speed of the wheels at the initial instant (t = 0). (b) Calculate the total number of revolutions each wheel rotates before coming to rest. (c) Calculate the angular acceleration of the wheel (d) Calculate the time it takes to...
A train slowing to a stop has an average acceleration of -3.00 m/ s 2 . If its initial velocity is 30.0 m/s, how far does it travel in 4.00 seconds? A.) 144m B.) 140m C.) 96m D.) 96.0m
A cart with a fan attached is pushed to the right with an initial velocity of 0.6 m/s. The fan on the cart causes a constant acceleration to the left of 0.2 m/s2 , so that the cart slows to a stop and then starts to travel to back the left. How far does the cart go to the right before it momentarily comes to a stop? Please show work/explanation! A. 0.12 m B. 0.90 m C. 1.2 m D....
Freight trains can produce only relatively small acceleration and decelerations. (a) What is the final velocity (in m/s) of a freight train that accelerates at a rate of 0.0700 m/s for 8.00 min, starting with an initial velocity of 4.00 m/s? m/s (b) If the train can slow down at a rate of 0.450 m/s2, how long (in s) will it take to come to a stop from this velocity? (c) How far (in m) will it travel in each...
