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.

Question

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.

Answer 1

a. F=ma

a= F/m=270/13.5

b. vf= a t

c. d=1/2 a t^2

Answer 2

Thank you.

Can you explain d=1/2 a t^2.

What does the ^ mean?
