2) An object is thrown directly upward with an initial speed of 25.0 m/s and returns along the same path to its initial position.
Once thrown into the air, the only influence on the object is gravity, so we
can conclude that the acceleration acting on the ball is the one due to gravity g= 9.8 m/sec^2
a) Calculate how long will it take the ball to reach its peak (its maximum height).

b) Calculate the maximum height that the ball will reach.

Place me with this question is my last question

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
