Complete Question
The displacement (in centimetres) of a particle moving back and forth along a straight line is given by the equation of motion
s = 4 sin(πt) + 2 cos(πt),
where t is measured in seconds. (Round your answers to two decimal places.)
(a) Find the average velocity during each time period.
i. [1,2]
ii. [1 ,1.1]
iii. [1, 1.01]
Answer:
Step-by-step explanation:
From the question we are told that
Equation of motion is given by
Generally equation for average velocity is mathematically given by
a) Co-ordinate(1,2)
b)Co-ordinate(1,1.1)
c) Co-ordinate(1,1.01)
0.2x + 0.7(50) = 0.4(x + 50)
0.2x + 35 = 0.4x + 20
35 = 0.2x + 20
15 = 0.2x
75 liters = x
Answer:
The girls worked together on their art project for 1 hour and 50 minutes.
Step-by-step explanation:
In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.
Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:
5-1=4
Then, you have to increase the minutes on the time they finished working by 60:
15+60=75
Now, you have to subtract the minutes which would be 25 from 75:
75-25=50
Finally, you have to subtract the hours which would be 4 minus 3:
4-3=1
The result would be 1 hour and 50 minutes.
According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.
