tatyana61 [14]

Answer:

54.67 N

Explanation:

The total energy produced is the product of power and time duration:

E = Pt = 82 * 1 = 82 J

Which is converted from work, product of forced extended over a displacement

W = E = Fs = F*1.5 = 82

F = 82 / 1.5 = 54.67 N

So the magnitude of the force exerting on the handle is 54.67 N

A model airplane of mass 0.6 kg is attached to a horizontal string and flies in a horizontal circle of radius 6 m, making 1.6 re
nikitadnepr [17]

Answer:

speed= 12.15\frac{m}{s}

Explanation:

In this question we have given

mass of airplane=.6 Kg

Radius of horizontal circle,r=6m

Time taken to complete 1.6 revolution=5s

Therefore time taken to complete 1 revolution, t=\frac{5}{1.6}

t=3.1 s

We have to find the speed of airplane

We will first find the distance covered by airplane in tracing one circle which is equal to circumference of circle

We know that

Circumference,d = 2 \pi \times r

or d=2\times 3.14 \times 6

d=37.68 m

We know that speed=\frac{d}{t}............(1)

Put value of d and t in equation 1

speed=\frac{37.68}{3.1}

speed= 12.15\frac{m}{s}

What is the acceleration of a 3 kg rock that is thrown with a force of 18 N?
Ket [755]

Answer:6m/s^2

Explanation:

Mass =3kg

Force=18N

Acceleration =force ➗ mass

Acceleration =18 ➗ 3

Acceleration =6

Acceleration =6m/s^2
