Auniform solid sphere with a mass of m = 390 grams and a radius r = 19.0 cm is rolling without slipping on a horizontal surface at a constant speed of 4.00 m/s. it then encounters a ramp inclined at an angle of 15.0 degrees with the horizontal, and proceeds to roll without slipping up the ramp. use g = 10.0 m/s2. how far does the sphere travel up the ramp (measure the distance traveled along the incline) before it stops for an instant?

l = 4.33 m

Explanation:

given,

mass of solid sphere = 390 gram = 0.39 kg

radius = R = 19 cm = 0.19 m

rolling with constant speed = 4 m/s

angle with horizontal = 15°

acceleration due to gravity = 10 m/s²

using energy conservation

I for sphere

        v = r ω

h = 1.12 m

l = 4.33 m

the sphere will travel 4.33 m on the ramp.

the amount of current in the coil

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
