A 0.500-kg block, attached to a spring with length 0.60 m and force constant 40.0 N/m. is at rest with the back of the block at point A on a frictionless, horizontal air table ( Fig. P7.69 ). The mass of the spring is negligible. You move the block to the right along the surface by pulling with a constant 20.0-N horizontal force, (a) What is the block’s speed when the back of the block reaches point B . which is 0.25 m to the right of point A ? (b) When the back of the block reaches point B . you let go of the block. In the subsequent motion, how close does the block get to the wall where the left end of the spring is attached?

In the Donkey Kong Country video games you often get around by shooting yourself out of barrel cannons. Donkey Kong wants to launch out of one barrel and land in a different one that is a distance in x of 9.28 m away. To do so he launches himself at a velocity of 22.6 m/s at an angle of 30.0°. At what height does the 2nd barrel need to be for Donkey Kong to land in it? (measure from the height of barrel 1, aka y0=0)
For which value of θ is the range of a projectile fired from ground level a maximum?
90° above the horizontal
45° above the horizontal
55° above the horizontal
30° above the horizontal
60° above the horizontal
A map from The Legend of Zelda: The Breath of the Wild shows that Zora's Domain is 7.55 km in a direction 25.0° north of east from Gerudo Town. The same map shows that the Korok Forest is 3.13 km in a direction 55.0° west of north from Zora's Domain. The figure below shows the location of these three places. Modeling Hyrule as flat, use this information to find the displacement from Gerudo Town to Korok Forest. What is the magnitude of the displacement? Find the angle of the displacement. Measure the angle in degrees north of east of Gerudo Town.
