On Land, a 5000kg amphibious vehicle can accelerate from rest to 10 m/s in 25 sec.
a)Final Kinetic Energy?
b)Avg Power furnished by engine during acceleration?
c)If the same power is required to propel the vehicle through water at a constant 2 m/s, What is the magnitude of the resistive force being overcome?
The attempt at a solution
I havent learn or dont know what is the meaning of Resistive Force, I tried searching for a formula online but they do not make sense.
