A coin slides down a ramp angled at 30∘ with respect to the horizontal. If the coin starts from rest, what is its speed in m/s after sliding 1 m?
The acceleration of an object on a ramp is a=mg*sin(x), where g=9.8 m/s^2 and x is the angle.
The Attempt at a Solution
I know that the acceleration of the coin is 4.9 m/s^2. that means that in the first second it will be travelling at 4.9 m/s, the second second will be 9.8 m/s, then third second 14.7 m/s, etc. However I don't know how to calculate the speed when the time is not an integer. For example, what is the speed of the coin after 2.3 seconds?
