Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.

You and four of your friends are all interested in getting out of town for a break. Two of your friends just want to relax while the other two want to get some exercise. You need some quiet time to study. To satisfy everyone, the group decides to spend the day canoeing on the river. Two people will put a canoe in the river and just drift downstream with the 1.5 km/h current. The second pair will begin at the same time as the first from 10. km downstream. They will paddle upstream until the two canoes meet. Since you have been canoeing with these people before, you know that they can paddle at 4.0 km/h in still water. When the two canoes meet, they will come to shore and you should be there to meet them with the picnic lunch. You decide to go to that spot ahead of time so you can study while you wait for your friends. How far from where the drifters launched will you wait for them? After lunch you decide to paddle across the river, which is 0.50 km wide. You can paddle 3.0 km/h in…
Rising fast ball. A batter in a baseball game will sometimes describe a pitch as being a rising ball, termed a hop. Although technically possible, such upward motion would require a large backspin on the ball so that an aerodynamic force would lift the ball. More likely, a rising ball is an illusion stemming from the batter's misjudgment of the ball's initial speed. The distance between the pitching rubber and home plate is 60.5 ft. If a ball is thrown horizontally with no spin, how far does it drop during its flight if the initial speed vo is (a) 36 m/s (slow, about 80 mi/h) and (b) 43 m/s (fast, about 95 mi/h)? (c) What is the difference in the two displacements? (d) If the batter anticipates the slow ball, will the swing be below the ball or above it?
