1. A particle moves with curvilinear motion with coordinates given by - :2 4t + 20 and y -3sin2t Determine at t=3 seconds: (a) the magnitudes of velocity and acceleration vectors, and (b) the angles which these vectors make with the x-axis. 2. With what minimum horizontal velocity u can a boy throw a rock at A and have it just clear the obstruction at B? (Note e 0, here). 40 m u B 26 m 16 m 3. A projectile is launched from point A with the initial conditions showni in the figure. Determine the distance s which locates the point of impact B. Also calculate the time of flight t. vo = 120 m/s A 0 40Β° 20Β° 800 m 8 B
