An angry bear throws an entire human being (55 kg) at an initial velocity of 14 m/s at an angle of 46 degrees.?
What is the total time of flight? What is their maximum height? What is the horizontal distance? Assuming the collision with the earth in total took 0.27s, what is the force of impact?
A 18 kg coyote is running at 14 m/s to catch its 4kg cub which is traveling at 3 m/s. What is the final velocity of their combination?
If the collision takes 3s, what is the force applied on the coyote by the cub? Two protons combine with two anti protons. What is the energy that is created by this combination? (mproton=1.67*10-27kg)

Welcome to Yahoo!Answers. One question per post, please.
There are equations for this:
Time of flight t = 2·V·sinΘ/g
max. height h = (V·sinΘ)² / (2g)
range x = V²sin(2Θ)/g
For V = 14 m/s
and Θ = 46º
and g = 9.8 m/s², I get
a) t = 2.1 s
b) h = 5.2 m
c) x = 20 m
