Hi could someone please show me how to solve this problem?
A car with a mass of 1500 kg is traveling at 25 m/s. The driver slams on the brakes and stops in 4.0 s. What was the force required to stop
Would someone please be able to provide the steps in solving this question? The questions goes as follows: Paris Hilton does 1300J of work as she pulls on her dogs leash at an angle of 43 degrees whil
This is quite interesting.I think here we have to apply a little bit of physics and a little bit of chemistry as well. Oh, Yes, little bit of Bio-logy also.When we mean smell oh, Yeah, where does it c

2. Find the average velocity of a race
In some physics questions vi, vf, or a are equal to 0. How do you know if they are or not?-If the object starts at rest, the initial velocity (vi) is 0.
If the object comes to a stop, the final veloci
I need to know the forward force in newtons that an actual electric train has. I cant find this value on the internet, so Im assume the easiest way is to use Fnet = ma. I know the top speed of the tra
