A dragster reaches 350 km/h from rest in 6.2s. If the car is 800 kg and generates a driving force of 1600n. Find the force of friction acting on the car.

Question

nikato · Answer

i think the first step is to convert 350 km/h to m/s

anonymous · Answer

97 m/s

nikato · Answer

i like to round to the nearest hundredth so 97.22m/s

next we find the acceleration of the car.

remember acel.= change in velocity/change in time

anonymous · Answer

15.68

nikato · Answer

yes. and the units is m/s^2

nikato · Answer

next is this euqation you should you.

total force exerted by the car - force from fiction= driving force

nikato · Answer

you can think of it like

the force made by the engine
MINUS fricion force because it is going opposite 

and this equals the actual force you are using to drive.

does this make sense?

how do i find those two
