rocket powered sledge accelerates at 35ms-2 and takes 1.6s to pass through a 60m section of a test track. Find the speed at which it entered the section what was its speed when it left?
I think this is the equation to use x=ut + 1/2at2 and than use a=v-u/t to get v ?
a= 35m/s
t= 1.6s
u=?
v=?
x= 60m
please show your working
thanks
