how would we do this without knowing the time it took to decelerate

[RoamMeYo]

Phew! 6:30, just divide the 'X' km/h by 3.6 and you will get the m/s.

[sonia]

Or an easier way is to divide km/h by 3.6 or multiply it by 3.6 to go from m/s to km/h

thank you so much for this video! really helped me out.

[kashdashortsman]

what is the first equation that you mentioned

[Antisocial]

from 60km/h it takes 1, 85s to get to 0?

[ahpinge]

Me: Scientific calculator... *_-Clicks Clicks-_*

[av]

km/h to m/s is 3.6 easy conversion to remember becasue 60minutes x 60 seconds/1000 metres = 3.6

[hansu-kundomaru]

You may also get the time by dividing the the initial velocity over acceleration and cancel meter however, in seconds square of two must be subtract unto the power of one. Hence the answer would only be seconds.

for the last part you could ave just done 16.7/9 lol still gives you 1.85
