A car

A car weighing 1.05 tonnes driving at the maximum allowed speed in the village (50 km/h) hit a solid concrete bulkhead. Calculate height it would have to fall on the concrete surface to make the impact intensity the same as in the first case!

Correct result:

h =  9.6451 m

Solution:

m=1.05 t kg=1.05 1000  kg=1050 kg v=50 km/h m/s=50/3.6  m/s=13.88889 m/s  g=10 m/s2  v=gt t=v/g=13.8889/10=25181.3889 s  h=12 g t2=12 10 1.38892=3125324=9.6451 m



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
