Answer:
No, the ball will not clear the fence.
Solution:
Angular velocity, 
Height, h = 1.2 m
Angle, 
Distance covered by the ball, d = 110 m
Length of the fence, l = 1.2 m
Radius of the axis, R = 46 cm = 0.46 m
Now,
To calculate the linear velocity of the ball, v:
Total time taken:
The distance at which the ball falls, with a = 0 is given by:
Since, the ball has to clear a fence 1.2 m long and a t a distance 110 m away, clearly it will not be able to cross it.
Answer:
317.52 mi/hr
Explanation:
First convert Meters into miles as the answer is required in miles/ h
1000m = 0.62 mi
Now, convert second into hours
7.45s = 0.0001 hr
The speed of the boat would be
v = 0.62/0.0001
=317.52 mi/hr
The green is ground. Ideally, no current travels in this one. The red and black are the power and neutral wires but which colors they are depends on a convention. In the US, you will actually have a black (power) and a white (neutral) Here it's red and black and usually in a red/black system the red is the power. Either way there is a potential of 120V rms between them.
Answer:
16.1
Explanation:
165 = 4 + ( 10 ) T
165 = 4 + 10T
Subtract 4 on both sides,
165 - 4 = 10T
161 = 10T
10T = 161
Divide 10 on both sides,
T = 161 / 10
T = 16.1
Linear momentum has to be conserved. It was zero before the thread eas burned ... when nothing was moving ... so the momentum of the masses moving in opposite directions has to add up to zero. ... Momentum = mass times speed. ... In one direction, you have 5 kg times 1/5 m/s= 1 kg-m/s. ... We need 1 kg-m/s in the other direction. ... 7 kg times speed = 1 kg-m/s. ... Can you finish it from here ?
