Hi guys.
Thank you for your input. I am trying to work through all your replies, and applies these into an answer; which I am having difficulity doing. The level of this question is aimed at A Level Physics (18 yo). I have not worked with Physics for over 10 years, so it all seems blurred into...
Forgot to show my attempt...
Force = change of momentum/time
33.23N = (75 x 10) - (75 x 0)/time
33.23N = 750/time
time = 750/33.23 = 22.6s
It will take 22.6s to come to a complete stop.
Find distance = S = 1/2 (v-u) x t
S = 1/2 6 x 22.6...
Background question:
A bicycle and rider have a combined mass of 75 kg. They freewheel down a slope whose maximum height is 6 meters above sea level. The slope is 20 meters long. At the end of the slope, the bicycle and rider are traveling with a velocity of 10 m/s. Calculate the work done...
Hi.
I am new to PF and I hope to learn some Physics, and chat to like-minded people.
I am currently taking an Access to Science course, which is the equivalent to 3 A Levels - Biology, Chemistry and Physics.
Hope to learn from you guys!
