37. 39-42 A particle is moving with the given data. Find the position of the particle. 39, v(t) = sin t-cos t, s(0) 0 40, v(t)= 1.5vr, s(4) 10 41. a(t) 10 sin t + 3 cos s(0) 42. a(t) = t2-4t + 6, s(0) = 0, 0, s(2m) s(1) = 20 12 43. A stone is dropped from the upper observation deck (t Space Deck) of the CN Tower, 450 m above the grour (a) Find the distance of the stone above ground level a time t. (b) How long does it take the stone to reach the grour (c) With what velocity does it strike the ground? (d) If the stone is thrown downward with a speed of 5 m/s, how long does it take to reach the ground
