alright i have 3 questions:1.A force does +130 J of work when it acts on a moving object and its direction is in the same direction as the object’s displacement. How much work does this force do when the angle between it and the object’s displacement is 56°?2.A 30-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, her kinetic energy decreases to 220 J from 410 J. How high does she rise during this interval? Neglect air resistance.3.A box is sliding up an incline that makes an angle of 32.6 ° with respect to the horizontal. The coefficient of kinetic friction between the box and the surface of the incline is 0.106. The initial speed of the box at the bottom of the incline is 4.44 m/s. How far does the box travel along the incline before coming to rest?
