Initial velocity= ${V}_{0}$

Velocity after t times $v(t)={v}_{0}+at$

a=acceleration

s=total distance

$s=4t+\frac{1}{2}a{t}^{2}$

$300=10\times u+\frac{1}{2}\times 6\times 100$

300=10 u +300

10u=0

u=0

option (c) correct

Solve the following differential equation dx/dy=-[(4y2+6xy)/(3y2+2x)]

The velocity distribution for laminar flow between parallel plates is given by:

$\frac{u}{{u}_{max}}=1-{\left(\frac{2y}{h}\right)}^{2}$

where h is the distance separating the plates and the origin is placed midway between the plates. Consider a flow of water at ${15}^{\circ}C$ , with ${u}_{max}=0.30\frac{m}{sec}$ and $h=0.50\text{}mm$ . Calculate the shear stress on the upper plate and give its direction.In August 2013, E*TRADE Financial was offering only 0.05% interest on its online checking accounts, with interest reinvested monthly. Find the associated exponential model for the value of a $5000 deposit after "t" years. Assuming that this rate of return continued for 7 years, how much would a deposit of $5000 in August 2013 be worth in August 2020? (Answer to the nearest $1. )
