AI Thread Summary
To analyze the Nissan Leaf's performance, first determine the car's mass and add 74 kg for the driver's weight to calculate kinetic energy at 60 mph using the formula KE = 0.5 * mass * velocity^2. Next, apply the work-energy theorem to assess the total work required to reach this speed. Calculate the average power during the 9.9-second acceleration period and compare it to the Leaf's advertised engine power of 80 kilowatts. Differences in these values may arise from factors such as energy losses due to friction or inefficiencies in the electric motor. Understanding these calculations provides insight into the Leaf's performance capabilities.

1) find out the Nissan Leaf mass (the actual car), add 74 kg for a typical test driver's mass and clculate its kinetic energy at 60 mph.
2) apply the work energy theorem to find the total work done to get a speed of 60 mph.
3) Calcualte the average power during the acceleration period of 9.9s.
4) Compare the power you calculated in (4) with the Leaf's advertised engine power of 80 kilowatts and give at least one reason for any difference between the two values

Your help would be appricated .. Thanks :)

You will need to look up the leaf mass for that car, but what is the formula for kinetic energy?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
