Question

The equation of motion is \(\ s=2costy+3sint, t\le0 \). Find velocity/acceleration at time t. I took the derivative to find the velocity, but got 0...?

Answer 1

is that 2cos(ty) ?

Answer 2

Good catch! That's supposed to be a t only.

Answer 3

so \[s=2\cos(y) + 3\sin(t) , t \le0\] ?

Answer 4

Oops cos(t)

Answer 5

Well the velocity at time t is just the derivative. Can you differentiate that?

Answer 6

@Dido525 I tried, but I got 0, which doesn't seem correct.

Answer 7

Lets see:
