calculate the acceleration of a car that travels down a hillthat is 1.2 meters long in 2 seconds


a=f/m



all that i have down is the forula but there is no other variables.
--im stumped
 
Physics news on Phys.org
Use the constant acceleration motion equations. If you don't know them google motion equations
 
wow they are really confusing

is there a way i can get the solution without trying to figure them out?


how can i find the force if i don't even know the acceleration?
 
imm really pissed at my science teacher right now
 
wait... i have this nifty little equation you can use to calculate the acceleration with the final velocity... d=(vi)(t)+(1/2)(a)(t)^2 vi is the initial velocity, and that equals zero, so you can cut that out and use the d=(1/2)(a)(t)^2 and work the equation to equal a... that is all i am going to give you
