QUESTION: From ground level, you toss a 20 N marble vertically into the air. You notice that it is going at 25.0 m/s upward when it is 15.0 m above the ground. Find (a) the marble's speed as it left the ground and (b) its maximum height using the work-energy theorem. ANSWER IN COMPLETE SOLUTION AND WRITE A CONCLUSION FROM YOUR ANSWER.
The skateboarder shown below has a potential energy of 2,800 J at a height of 4 meters. Assuming there is friction on the track, how high will the skateboarder reach on the other side of the track? (5a; DOK 1) 2 O meters More than 4 meters because gravity will do positive work on the skateboarder. Less than 4 meters because friction will do negative work on the skateboarder.
