DYNAMICS

A balloon rises from the ground with a constant acceleration of 4ft per sec^2. Five seconds later, a stone is thrown vertically up from the launching site. What must be the minimum initial velocity of the stone for it to just touch the balloon? Note that the balloon and stone have the same velocity at contact.

Dynamics Kinematics

please help!

A ball is thrown down the incline strikes it a a distance s = 254.5 ft. If the height h = 64 ft. above the point of release, compute its initial velocity abd inclination theta.

(there is a given 3 for opposite, 1 for adjacent)

Restrained Beams Deflection

I have a question regarding Problem 719. I've got the correct answer for solving for R. But when i try to solve using my own way of solving the midspan deflection, my answer is wrong. So i consult your solution. Although your answer is the same as in the textbook, I was confused why the tangent line was drawn from B which is by inspection, the tangent line drawn from a fixed end is horizontal.

Thank you for your response.
