30. An astronaut and his space suit have a combined mass of 157 kg. The astronaut is using a 5.0 kg tool kit to repair a solar panel on the International Space Station. When the tether connecting the astronaut to the space station becomes unattached, the astronaut, still holding the tool kit, starts to float away at 0.2 m/s.
Calculate how far from the space station the astronaut will be after 1 minute. Show your calculations and include units in your answer.

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
