Question

the velocity of a body is given by V=At2 +Bt+C if V and t are expressed in S.I units what are the units of A, B, C

Answer 1

I hope it is helpful....

Answer 2

The expression for velocity is given as V= $At^2+Bt+C$;

Now we know that the SI unit for velocity is m/s so to make both side equal both the sides should have m/s as their SI unit

So, if $At^2= m/s$

                                        $As^2=m/s$

                                        $A = m/s^3$

Since si unit for time is second ‘t’ is replaced by s.

Similarly, Bt = m/s

                                        Bs=m/s

                                        $B=m/s^2$

And for C it should be m/s
