When a car moves from rest then the initial velocity,
u = 0m {s}^{ - 1}

The final velocity,

v = 25m {s}^{ - 1}
and time,
t = 30s
Using the equation,
v = u + at
We have,

25 = 0 + a(30)
25 = 30a
\frac{25}{30}  = a
\therefore \: a =  \frac{5}{6} m {s}^{ - 2}

A spherical snowball melts at a rate proportional to its surface area. (a) write a differential equation for its volume, v. (use
tresset_1 [31]

Answer:

Explanation:

The rate of change in volume is proportional to the surface area:

dV/dt = kA

Integrating:

V = kAt + C

At t=0, V = s, so:

s = kA(0) + C

C = s

Therefore:

V = kAt + s
