Answer:
9/16 inch
Step-by-step explanation:
A = 3/4 +1/16
B = 1/4
x = A - B
x = (3/4 +1/16) - (1/4) . . . an equation for the difference
x = (12/16 + 1/16) - 4/16 = (13 -4)/16
x = 9/16
The difference between A and B on the ruler is 9/16 inch.
Answer:
Vertical angle=9.5°
Time to reach maximum height = 1.24seconds
Step-by-step explanation:
The maximum distance x is reached when rope swings to a maximum height, maximum height is gotten from the equation KE= 1/2MU^2 = MgH = MgL= Mgl(1- cos theta.
Where theta is the vertical angle, U=2m/s and L= 15m
2gl -2glcostheta=U^2
2gl U^2=2gl cos theta
But theta= Acos(1- U^2)/2gl
Acos(1-/(2×9.8×15)
Theta =9.5°
Maximum height li given by
Lsintheta
But X= UxT
T=X/UX= Lsintheta/U = 15sin9.5 /2 =1.24seconds
