If the ball pictured below is released from the top of the ramp, what will be its translational speed(v) at the bottom of the ramp? (Let the height of the ramp, h = 2m; and, laphar = 2/5MR^2) h

A peak of a house roof is 8 m above the ground, The edge of the roof is 4 m above I take a cylinder (m = 400 gms, d= 8 cm) up to 9. the ground, roof pitch is 5" in 12", the peak and let it roll down, how far from the house wall does it land? m. As it hits the ground how fast is it spinning? rad/sec vaton is 0.9 me on Euuegrees to the h. urown waru- with a C.Parame Plut Lihe parh ton if ic is sp:- throw fro her using t it out

How do I find the tangential speed of a ball going in uniform circular motion, in the problem I'm working on, a 1.3 m long string makes a 48.8 degree angle below the hoizontal. I am confused as to how I find the w to plug into the Vt=rw equation to get the tangential speed. Thanks for your help!

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. A fire hose held near the ground shoots water at a speed of 12.5 m/s. At what angle(s) should the nozzle point in order for the water to land 6.69 m away? What is the lowest angle in radians?  What is the larger angle in radians?

Hi! I'm struggling with this question on my trigonometry homework about angular velocity and linear velocity.  A line from the center to the edge of a CD revolving 300 times per minute

A car drives in a circle of radius 100 m. The car travels for an angular displacement of 37rad37rad. This is equivalent to a linear distance around the circle of

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.89 times a second. A tack is stuck in the tire at a distance of 0.389 m from the rotation axis. Noting that for every rotation the tack travels one circumference, find the tack's tangential speed. tangential speed:? What is the tack's centripetal acceleration? centripetal acceleration: ?
