A car has a mass of 1200kg and delivers a total of 2300Nm of torque. Tyre radius of 0.306m. What is the acceleration of the car in m/s^2? What is the speed of the car if it has accelerated for 11 seconds? (determained in first question), I have looked at a few and still a bit stuck. A=m*R and then convert to m/s^2 or W=(fcos theta)(d) Attepted both and seem to still be getting the wrong answer.. A= 1200*0.306 = 367.2m/s^2 or W=(2300cos45)(0.306*2) = (1626.35)(0.612) = 995.3262 As you can see i am well off the right answer. I am more incline to think it is the equation A=m*R... Please help!!
