Please help
You are riding a bicycle and your speed up so you are going 4 times your typical speed. How will the bicycle's kinetic energy be effected? Your answer should be a number. Include the math to show how you calculated that number! ex) When the speed increased by 4x, the kinetic energy increased by _________. I calculated this by_______.

Answer:
f you had to pick the greatest machine of all time, what would you say? If we were talking about machines that helped spread knowledge and educate people, you'd probably opt for the printing press.

Answer:
Kinetic E =2×4 times your typical speed
When the speed increased by 4x, the kinetic energy increased by 16. I calculated this by ½m(4x²).
Explanation:
Kinetic energy of a body depends on its mass and its speed. Hence, ,kinetic energy(K.E) will become 4 times the original kinetic energy if the speed is doubled. (tkn frm web)
,ie, K.E = ½m(2v)² = 4(½mv²)
= 4× original k.E.

ur so helpful thank u ❤️
explanation is 100 corrct,, bt i may make sme mistk in calc,,
as i m confused newSpeed= 4x or (4x+x)
yea, the whole ans is 100 corrct,, i checked it.
remember... use short cut method in exm try to calc. shortly... if allowed
