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...

Thanks Bernhardt! I look forward to getting to know some of the amazing guys on here. Good to be part of the community!

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!
