a go-cart moves along a circular track of radius 100ft such that its speed for a short period of time , 0 is less than t which is less than 4s, is v=60(1-e^t^2)ft/s. Determine the magnitude of its acceleration when t=2s?
How do you figure this out while using Simpson's rule with n=50 to evaluate the integral?
