What i have worked out :
85th speed exceeds the limit by 24% = 37.mph.
travels at 16.63 m/s
average driver reaction time 1.5 seconds
16.63 x 9 = 149.67 m/s x 1.5 = 224.5
am i on the right wave lengths here, thanks for any help
Firstly thanks for your help. I have 1025 as my mass. 9.81gravity. 4m difference in height. PE=mgh.
This is what we had I'm class:
1025x2x2x9.81/6x60x60
200x10 to the power of 6.
Slightly confused how they got this.
Please could you help work through
