The theoretical equation, V IR, is known as "Ohm's Law. By coincidence the letter symbols for potential (a quantity) and volts (its unit) are identical. Thus "voltage" has become the laboratory slang name for potential. a. Rearrange the Ohm's Law equation to match y mx+ b b. What is the experimental resistance? c. Comment on the experimental intercept: is its value reasonable?

Explanation / Answer

61)

given

initial velocity, u = 2.52 m/s

final velocity v = 0

a = -0.65 m/s^2

a) let d is displacement of the ball before coming to stop.

use, v^2 - u^2 = 2*a*d

==> d = (v^2 - u^2)/(2*a)

= (0^2 - 2.52^2)/(2*(-0.65))

= 4.88 m

clearly 4.88 > 4.80

so, the ball make it to the hole.

b) let v is the ball's velocity when it make it to the hole.

let d = 4.80 m

use, v^2 - u^2 = 2*a*d

v^2 = u^2 + 2*a*d

v = sqrt(u^2 + 2*a*d)

= sqrt(2.52^2 + 2*(-0.65)*4.8)

= 0.332 m/s <<<<<<<<<<<<----------------------------Answer
