A car with mass 450kg has a Kenetic energy of 16256 J. what is the speed of the car ?

speed/velocity(v)=8.5m/s

Explanation:

soln:

given,

mass(m)=450kg

kinetic energy(K.E)=16256 J

speed/velocity(v)=?

we know,

K.E= 1/2*m*v^2

or,16256*2=450*v^2

or,√32512/450=v

•°•v=8.5 m/s

Based on what we have learned so far, in what ways have the experiences of Asian-Canadians stayed the same over time? Why do you think these similarities exist? Please give specific examples to support your ideas.
