Best ResponseYou've already chosen the best response.1Assuming a start from rest: \[d=Vi(t)+\frac{1}{2}at^2=0m/s^2+\frac{1}{2}(4m/s^2)(10s)^2=200m\]

Best ResponseYou've already chosen the best response.1Or, you can use: \[d=\frac{V_i+V_f}{2}t=\frac{0m/s+40m/s}{2}(10s)=200m\]

Best ResponseYou've already chosen the best response.1Well he used this formula x = ut + 0.5at^2

Best ResponseYou've already chosen the best response.1u = 0m/s , becausehe assumed the car started from rest

Best ResponseYou've already chosen the best response.1Then he plugged in the numbers x = 0.5*4* 100 = 200m
