velocity is 20sin (pi*t) find average velocity from 0 to 1sec

Expert Answer
velocity = ds/dt = 20 sin(πt) m/s
Hence, ds = 20 sin(πt) dt m ...................... (1)
By inetgrating eqn.(1), we get, S(t) = -( 20/π ) cos ( πt ) m .......................(1)
Hence displacement ΔS = S(1) - S(0) = (20/π) - [ - (20/π) ] = 40/π m ..................(2)
average velocity = ΔS / Δt = ( 40/π ) m/s
