 A spring-loaded toy gun shoots a <math display="inline"><mrow><mn>3.0</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">g</mi></mrow></math> plastic ball straight up into the air. From the position of the ball when the gun is cocked, with the spring compressed, to the maximum height the ball reaches, is <math display="inline"><mrow><mn>2.5</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">m</mi></mrow></math>. If the spring was compressed <math display="inline"><mrow><mn>2.0</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math>, what is the spring constant of the spring? Ignore air resistance. 

<p>You are practicing jumping as far as you can. In one attempt, you run and leave the floor with 7 m/s directed at an unknown angle. What maximum height do you reach if your speed at that point is 5 m/s? Ignore air resistance.</p>

 Calvin uses a catapult to launch a foam football at Susie. If the ball leaves the catapult at a height of <math display="inline"><mrow><mn>2.0</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">m</mi></mrow></math> and is moving at <math display="inline"><mrow><mn>15</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">m</mi><mo>/</mo><mi mathvariant="normal" class="MathML-Unit">s</mi></mrow></math> when it strikes the ground (he missed), how fast was the football moving when it left the catapult? Ignore air resistance. 

 A toy gun is mounted on a tabletop. It shoots a small plastic ball at <math display="inline"><mrow><mn>6.0</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">m</mi><mo>/</mo><mi mathvariant="normal" class="MathML-Unit">s</mi></mrow></math>. The ball leaves the toy gun at an angle of 24° above the horizontal, and a height of <math display="inline"><mrow><mn>83</mn><mo rspace="thickmathspace">&#x2062;</mo><mi mathvariant="normal" class="MathML-Unit">cm</mi></mrow></math> above the ground. How fast is the ball travelling when it hits the ground? Use energy concepts.
