An astronaut on the moon throws a baseball upward. the asatronaut is 6ft, 6in. tall, and the initial velocity of the ball is 30ft per second. the heigh s of the ball in feet is given by the equation s = -2.7^2 + 30t + 6.5, where t is the number of seconds after the ball was thrown. after how many seconds is the ball 16ft above the moon's surface?

Which statements describe how a machine can make work easier? check all that apply. it can put out more force than the input force by decreasing the distance through which force is applied. it can increase the amount of work performed if the output force is in the same direction as the input force. it can apply a force to an object in a different direction than the force applied to the machine. it can increase the distance through which a force acts by exerting less force than was used on it. it can exert a greater force through a greater distance than the force used on the machine.
