Please answer these questions:

1) A man stands on the edge of the roof of a 15.0-m tall building and throws a rock with a speed of 30.0 m/s at an angle of 33.3⁰ above the horizontal. Ignore air resistance. Calculate: the total time that the rock spends in the air?

2) A ball is thrown upward at an unknown angle with an initial speed of 20.0 m/s from the edge of a 45.0-m-high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored. At what angle above the horizontal should the ball be thrown so that the runner catches it just before it hits the ground, and how far does the woman run before she catches the ball?

Please answer all of the questions. Spider-Man and Spider-Woman are planning to have children in the near future. Spider-Man is able to spin webs (S) and cling to walls (C), whereas Spider-Woman can spin webs but cannot cling to walls. If both of these traits are inherited in a dominant manner (i.e., the dominant trait will always mask the recessive trait), Spider-Man is heterozygous for each trait, and Spider-Woman is heterozygous for the web-spinning trait...

A drunk man walking simulation A drunk man stands at origin. There is a cliff at x=10 and home at x=-10. He takes steps randomly left and right. Each step has the probability p of going left and q=1−p of going right. We desire to simulate and plot 100 random trajectories for the interval of 100 time instants. Once hit at home or cliff, a trajectory is stopped immediately and success or dead is declared. Otherwise, alive is declared. Obtain...
