Chapter 14: Kinetics of a Particle : Work and Energy
Hibbeler Dynamics 14th ed
14-13. The 2-lb brick slides down a smooth roof, such that when it is at A it has a velocity of 5 ft/s. Determine the speed of the brick just before it leaves the surface at B, the distance d from the wall to where it strikes the ground, and the speed at which it hits the ground.

Helped a ton, thanks!
Thank you!
you are saving me!
yes continue pls
Awesome, Thank you
No worries!
Thankyou Bhai
I found the distance d using trigonometry... The answer was 20.1
U can't use trigonometry here
The height 30 = Rsintheta,, R=20.1,, d = square root R^2+30^2
