Apparently you have already answered question 1. If not, see the "related Question" below. Question 2: If the ball starts at a height of Ho = 44 m, if loses the available kinetic energy until it reaches the maximum height Hmax g*Ho + Vo^2/2 = g*Hmax (Hmax-Ho)= Vo^2/(2g) = 45.9...

**physics, please help me, this question is hard**

a. Vf^2 = Vi^2 + 2*a*d solve for Vi given Vf = 0 (speed at max height is 0), a = -9.81 m/s^2 and d = 3m. b. Once you know Vi, you can use Vf = a*t + Vi and solve for t. (once again, Vf = 0 since you're only considering the path of the ball from the top of the building to ...

The direction (25 degrees north of east) is useless information. You can ignore it. If it is in the air 3.0 seconds,it takes 1.5 seconds to rise to maximum height. The vertical velocity component is g*1.5s = 14.7 m/s To compute how far the arrow goes, you need to know the ...
