Homework Statement
An object is initially at rest, then, it receives a various acceleration a.
The acceleration is a function of its displacement d, given by the function a = cos (d/5 metre)
What is the object's velocity after moving 3 metres?
Homework Equations
d = 0.5*a^2
a = cos(d/5m) (question specific)
The Attempt at a Solution
This probably requires integration, of which I have basic understandings.
(Oh by the way, this is originally a problem dealing with a catapult, where the catapult's shaft is receiving a torque that varies with time (gravity's direction is unchanged but the tangent's direction does change) and I needed to calculate the final angular velocity after the shaft rotates a certain amount of angles. I thought the principle applies to linear motion too.)
