We are going to be late for the hockey game in Toronto. It's 250km from here and the game starts in 2 hours.
You're right, if we average a velocity of 95 km/h (forward), it will take us over 2.5 hours to get there.
What if we flew to the game?
That is an option we could do. It would give us a faster speed due to no traffic and bigger engines, and it might get us to the game on time.
How are you guys able to the calculations so quickly?
It's actually quite easy Sarah, for example for converting km/h to m/s you would do you would do take the velocity 85km/h dived by 3.6 and get 24m/s.
Which equation would I use if I was trying to figure out velocity of an object if it went 100km (north) then 50 km (east)?
You would use co sin law, a square plus b squared equals c squared. So you would do 100 squared plus 50 squared equals 12,500. Then you would square root 12,500 and that is your velocity, 110km/h.
We might be able to make the game, due to this car has really fast acceleration and if we take highways with less vehicles and more open space to use the cars acceleration abilities, we might make it on time.
That is true Ben, what is the cars 0-100km/h?
The car will be able to do now 0-100km/h in under 4.0 seconds.
We might be able to make the game, see I mixed up and accidentally mistaken the distance for displacement. distance is how far you go in a trip adding up all the different things you did where displacement is how far we are from starting point, so we should actually make the game on time as the total distance there and back is 250km but the displacement is only 130km.
