Answer:

#1.64# volts to the nearest third sig fig

Explanation:

Let's break down it down into steps:

#m/s^2# is acceleration

#kg# is mass

#F=ma#

#m/s# is velocity

#P=Fv#

So the top half can be simplified to power which is measured in watts.

So far we have the units of watts over amperes

#P=IV#

#P/I=V#

The singular unit of watts over amperes would be volts.

Now that we have the units, we can work out the problem giving us #1.64# volts.
