Help i have brain ache, i need to know the kinetic energy at 120 mph ? please can someone help ?
No, because you have not specified the mass. (Don't pass on the headache to us.)
Hi all i have to go on is a train doing Normal speed for the X2000 is 200 km/h (120 mph),
For a mass m moving at speed v, KE = (1/2)mv^2 (in consistent units.)
Thankyou so much mate. I might be home and dry for your help.
