The Attempt at a Solution
v= 440 (4L) I'm just not sure how to use both lengths given, can someone...
Does anybody know if it would work to use the kinematic equation vf2 = vi2 +2ad? I have all the variables to solve for final velocity. But I'm not sutre if it's different because it applies to a curved ramp. Plus this is in the work/energy unit so i don't know why my teacher would want me using...
Homework Statement
I need to find the horizontal velocity of an object on a ramp where the first height is 5.0m and the second height is 3.0m? I also need to find the time it takes to fall from the ramp, and the distance it falls away from the ramp. I am only given the two heights, an initial...
Homework Statement
So I have a block that has had a bullet shot through it at an initial speed of 280m/s. It is 0.03kg and after it leaves the block it is traveling at 190m/s. The block is a length of 0.012m and weighs 1.50kg. What is the average force exerted on the block?
