A car with a mass of 900 kg accelerates at 45 m/s 2 squared. What is the force acting on the car?

mass (m) = 900 kg, acceleration (a) = 32 m/s^2. using f=m*a, f = 900 * 32 = 28 800 newtons. power (watts)= (f * s)/t say accelerating for 1 second from rest, s= (a*t^2)/2 = 16 meters.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

um i think it might be a car?
