A 10.9 kg disk with a radius of 0.14 m is released from rest at the top of a 2.7 m tall ramp. What is the (translational) speed of the object when it reaches the end of the ramp? Report your answer in meters per second, rounded to one decimal place

Consider the following situation: A 0.7 kg box is released from rest at the top of a 1.35 m tall ramp. The ramp is smooth, and friction may be neglected. At the bottom of the ramp is a 2.0 kg box. When the two boxes collide, they remain stuck together with Velcro. What is the speed of the two boxes after the collision? Report your answer in m/s, rounded to two decimal place
