erik [133]

Answer:

P = 36068.7 Watt

Explanation:

As we know that average power is the ratio of total work done and total time interval

so we will have

Power = \frac{Total \: Work}{time}

now we know that

Work = \frac{1}{2}mv^2 + mgh

W = \frac{1}{2}(700)(11^2) + 700(9.8)(9.6)

so we will have

W = 42350 J + 68856 J

W = 108206 J

now power is given as

P = \frac{108206}{3}

P = 36068.7 Watt

Camping equipment weighting 5000N is pulled across a frozen lake by means of a horizontal rope. There is a frictional force of 3
Dmitry [639]

Answer:

The work done by the campers is 4\times10^{5}\ J

(b) is correct option.

Explanation:

Given that,

Weight = 5000 N

Frictional force = 300 n

Distance = 1000 m

Constant rate of speed = 0.20 m/s²

We need to calculate the force

Using newton's law of motion

F-F_{\mu}=ma

F-300=\dfrac{5000}{10}\times0.20

F=\dfrac{5000}{10}\times0.20+300

F=400\ N

We need to calculate the work done

Using formula of work done

W=F\times d

Put the value into the formula

W=400\times1000

W=4\times10^{5}\ J

Hence, The work done by the campers is 4\times10^{5}\ J
