Question

Please show all work and use formulas used. Im trying to learn

A ball is placed in a parabolic well in the figure. The balls mas is m

A) Find F(alpha) and Fy components of the total force acting on the ball using Newtons Laws. Hint using a slope angle alpha might help

B)Find forces acting o the ball using potential energy

C)Explain the difference of the results in A and B if any Hint we/you might be solving different problems in A and B. In other words there is a mistake in B what is it? Explain

Figure 1

Explanation / Answer

(A)f=fx+fy

=fsin+fy

=fmt+fh

(b)in potential enegy force acting on ball

f=mgh

the difference of the results in A and B it is different as in part(A)force acting in both direction in x and y both while in (B) force is acting only toward ground making both the all others factors zero.
