Best ResponseYou've already chosen the best response.0at t=0 the velocity of the particle is 2. for what value t will the velocity of the particle be zero?

Best ResponseYou've already chosen the best response.0To find a velocity equation from an acceleration equation, you need to differentiate the acceleration equation with respect to t: \[a'(t)=\cos(t)\]Now find the values for which this equation is equal to 0. \[0=\cos(t)\]\[t=\pi/2, 3\pi/2\]

Best ResponseYou've already chosen the best response.3\[v(t)=\int a(t)dt=\frac1 2t^2\cos t+C\]\[v(0)=12=C=3\]\[v(t)=\frac1 2t^2\cos t3=0\]solve for t

Best ResponseYou've already chosen the best response.0think this might be backwards you are given acceleration and you want velocity
