Question

If v=u+at find u, when v =103.
a=5 and t=9.5​

Answer 1

u = 65.6

Explanation:

Use the equation v = u + at and substitute the given terms.

103 = u + (5) (9.5)

Simplify the (5) (9.5) by multiplying (47.5) you then have:

103 = u + 47.5

You want to isolate the variable (the u) and to do that you need to subtract 47.5 from both sides. This leaves you with 65.5 = u
