Asked by Steph
A force of 270N acts on a mass of 13.5kg for 13sec. Calculate a) the acceleration b) the final velocity c) the distance covered.
a)F=m*a, so 270=13.5*a/13, answer 260m/s
b)Not sure which formula.
c)Formula d=v*t, once velocity is worked out in question b).
I am not sure with a) either.
Thank you kindly.

a. F=ma
a= F/m=270/13.5
b. vf= a t
c. d=1/2 a t^2
a= F/m=270/13.5
b. vf= a t
c. d=1/2 a t^2

Thank you.
Can you explain d=1/2 a t^2.
What does the ^ mean?
