- A red 150 g toy car slides down a 40 degree frictionless ramp. At the bottom, just at it exists onto a horizontal part of the slide, it collides with a purple 400 g car at rest. How high should you make the water slide so that the red toy car gives the purple car a speed of 300 cm/s?Box 1 (with mass m = 7.1 kg) is on a frictionless table moving with a velocity Vo = 7.1 m/s. It collides with an identical box (let's call it box 2). The boxes stick together and launch horizontally off the table. What is the kinetic energy of the boxes when they land on the ground a distance H = 1.4 m below the table? H 1 Vo 2 1 dA 70 kg space voyager is stranded on a 700 kg escape pod that has left the main spacecraft and is floating in free space (you may assume its velocity is 0 m/s). A rescue ship is approaching and will pass within 100 m of the escape pod. The space voyager plans to push herself away from the escape pod towards the point by which the rescue ship will pass (point P in the diagram). The space voyager knows that she can apply a constant force of 100 N while she pushes for the 0.50 s it takes her to straighten her arms. (a) What will her velocity be after she has finished pushing against the rescue pod? (b) How long before the rescue ship is due to arrive a point P should the space voyager begin her push?
