AS Further maths mechanics and decision

Can anyone remember any answers they got for the Edexcel fm1 and d1 exam today
Here’s my answers for Further mechanics:

Q travelled at 7/2 u
Velocity of the race car was 40m/s, you had to convert that to km/h though
Velocity when going uphill: 20m/s
Initial Velocity of the stone: 24m/s
Distance into the ground: 7cm
KE loss was 5mu^2(2-3e)/6

Hi if u don’t mind me asking, how did you work out the distance into the ground. I tried it but couldn’t get it.

for the question with the distance as 7cm how did you get that because in the question it said d cm so i converted d cm into meters which is 0.01d meters then i did the calculation and i got d as 783 cm to 3sf as at the end you multiply by 100 to turn it back to cm I did this because height is always in meters in these calculations

Hi, do you remember any other questions as well as their answers? If you could explain how to do them that would be great as well :smile:
