1000 m/s
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Energy in spring:
<span>E = ½k · x²; where x = 0.15m </span>
<span>From coefficient of friction, </span>
<span>F = µ · N = µ · mg; where m = 5kg and g = 9.807m/s² </span>
<span>Work done each pass = </span>
<span>W = ∫Fdx = Force · distance </span>
<span>Just divide E by W to see how many passes, use this to figure out where it stops. </span>
Answer:
Total distance = 400+700+1200= 2300km
Explanation:
the resultant of d 1st right angle triangle + 1200
= 806.2 + 1200 = 2006.2km
Answer:
Hi I hope this is correct!
Explanation:
To find average velocity you can use the formula av = (v1 + v2) / 2
*I converted everything into m/s because that it usually the measurement for velocity*
v1 = initial velocity = 8.49376 m/s , v2 = final velocity = 33.528 m/s
av = 8.49376 + 33.528 / 2
= 21.01088 m/s
*If you were required to leave the final answer in mph here it is
av = 19 + 75 / 2
= 47 mph
Hope this helps! Best of luck <3
