Can someone help with this

@cobalt condor Greatest speed will be V in Suvat. We have values for U,a,t so use equation V=U+at. Sub in your values for U (18), a(2.4), t(5) and then you have your maximum speed

#

That’s for part a ^^^^

#

I assume this is what you do for part B.

#

You need the value for t

#

And we have values for U,a,s

#

We can use the equation, S=Ut+1/2at^2

#

Rearrange this equation for t.

#

Then sub in your values to find the time.

#

U is the value you found in part a.

#

S is 300

#

A is 0 as there is no acceleration as travelling at a constant speed.

#

Hope this helps
