icture the situation where a ball is attached to the end ofa string. By whirling the ball with the string, you can make it move around in a horizontal circle at constantspeed.(a) What is the netverticalforce on the ball? Sketch a free-body diagram of the forces acting on the ballfor some point in its circular orbit.(b) What must be the direction of the ball’s acceleration to keep it moving in a horizontal circle?(c) From your free-body diagram in part (a), determine the net force acting on the ball. Does this agreewith part (b)?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
