please show work, thanks. 5. A 2000 kg car accelerates from 10.0 m/s to 30.0 m/s....
PLEASE SHOW WORK AND PLEASE DON'T GET IT WRONG THIS
TIME!!!
1.
A 1940 kg car moving at 20.0 m/s collides and locks together with a 1540 kg car at rest at a stop sign. Show that momentum is conserved in a reference frame moving at 10.0 m/s in the direction of the moving car. initial momentum _______ kg.m/s final momentum _________ kg.m/s
018 (part 1 of 2) 10.0 points A 1.01 × 10° kg car accelerates uniformly from rest to 11.5 m/s in 2.32 s. What is the work done on the car in this time interval? Answer in units of J. 019 (part 2 of 2) 10.0 points What is the power delivered by the engine in this time interval? Answer in units ofW.

3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...
A 2000 kg car strikes a wall at 15 m/s and comes to a stop in .15 seconds. With how much force did the car strike the wall? Please show all work.
In a test run, a certain car accelerates uniformly from zero to 24.0 m/s in 2.95 s. (a) What is the magnitude of the car's acceleration? (b) How long does it take the car to change its speed from 10.0 m/s to 20.0 m/s? (c) Will doubling the time always double the change in speed? Why?
Please let it be legible, thanks in advance!
