(b) Suppose oil spills from a ruptured tanker and spreads in a circular pattern. If the radius of the oil spill increases at a c
andreyandreev [35.5K]

Answer:

\frac{dA}{dt} \approx 245.044\,\frac{m^{2}}{s}

Explanation:

The formula for the surface of the circle is:

A(r) = \pi\cdot r^{2}

The rate of change of the spill area is obtained by deriving the previous formula in terms of time:

\frac{dA}{dt} = 2\pi\cdot r\cdot \frac{dr}{dt}

Finally, variables are replaced by known data:

\frac{dA}{dt} = 2\pi\cdot (39\,m)\cdot (1\,\frac{m}{s} )

\frac{dA}{dt} \approx 245.044\,\frac{m^{2}}{s}

A 6.00 kg object is lifted vertically through a distance of 5.25 m by a light string under a tension of 80.0 N. Find: (2 marks)
jeka57 [31]

Explanation:

It is given that,

Mas of the object, m = 6 kg

It is lifted through a distance, h = 5.25 m

Tension in the string, T = 80 N

(a) By considering the free body diagram of the object, the forces can be equated as :

T-mg=ma

a=\dfrac{T-mg}{m}

a=\dfrac{80-6\times 9.8}{6}

a=3.33\ m/s^2

Work done by tension, W_t=F\times h

W_t=80\times 5.25

W_t=420\ J

(b) Work done by gravity, W_g=mgh

W_g=6\times 9.8\times 5.25

W_g=308.7\ J

(c) Let v is the final speed of the object and u = 0

v=\sqrt{2ah}

v=\sqrt{2\times 3.33\times 5.25}

v = 5.91 m/s

Hence, this is the required solution.
