A diving board of length L = 3.00m is supported at a point a distance 1.00m from the end, and a diver weighing 530N stands at the free end. The diving board is of uniform cross section and weighs 295N.
A) Find the force at the support point.
B) Find the force at the end that is held down.
The electric potential inside a conducting sphere is 245V, and a distance d = 32.0cm from the surface of the sphere, the potential is 175V. Calculate (a) the radius of the sphere and (b) the charge on the sphere.
What is the difference between a vector's x scalar component, How do equilibrant and resultant vectors relate to each other
a 1.5 kg block is held against a spring of force constant 18516 N/m compressing it a distance of 180 cm. How fast is the block moving after it is release
The potential for a mass hanging from a spring is V(y)=ky^2/2+mgy, when y=0 corresponds to the position of the spring when nothing is hanging from it. Find the frequency of small oscillators around the equilibrium point.
