2) A ramp has an incline of 25.0° above horizontal and is 2.40 meters long. A robotic arm pushes a 7.00-kg block up the ramp, exerting a 100.0-N force parallel

to the ramp. This force is exerted on the block by the robotic arm all the way up the ramp. If this block has been sprayed with silicone oil (to eliminate friction) and it has an initial velocity of 1.80 m/s at the bottom of a ramp, what is the speed of the block when it reaches the top of the ramp?
