Explanation:
<em>a)Which of the two has uniform acceleration?</em>
Acceleration is the second derivative of position. The acceleration of the first particle is:
x = 4t² − 2t
v = 8t − 2
a = 8
The acceleration of the second particle is:
x = 6t³ + 8t
v = 18t² + 8
a = 36t
The first particle has uniform acceleration.
<em>b)Which one is likely to come to rest at some time during its motion?</em>
The particles come to rest when v = 0. The first particle's velocity has a real zero at t = 4. The second particle's velocity has only imaginary zeros, meaning v is never 0.
Answer: Temperature in Fahrenheit is 577.4
Explanation:
The conversion factor for converting celcius to Fahrenheit is:
where F = temperature in Fahrenheit
C = Temperature in Celcius
Given : Temperature difference in Celcius = 
Putting in the values we get:
Thus the answer in Fahrenheit is 577.4
Angle is 31 adding all sides
Average speed =
(total distance covered)
divided by
(total time spent covering the distance)
