Answer:

The 39.

Explanation:

KE  =  1/2 · m · v²

1470 = (1/2 · 60) · (v²)

v²  =  1470 / 30

v²  =  49

v =  √49

<em>v  =  7 m/s</em>

<em></em>

(Note:  Kinetic energy has nothing to do with height above ground.)

Ruby is out with her friends. Misfortune occurs and
zhannawk [14.2K]

The work done is 2.35\cdot 10^5 J

Explanation:

The work done by a force on an object is given by:

W=Fd cos \theta

where

F is the magnitude of the force

d is the displacement of the object

\theta is the angle between the direction of the force and of the displacement

In this problem, we have

F = 1080 N is the force applied on the car

d = 218 m is the displacement of the car

And assuming the force is applied parallel to the motion of the car, \theta=0^{\circ}, and so the work done is

W=(1080)(218)(cos 0^{\circ})=2.35\cdot 10^5 J

Dvinal [7]

Answer:

4363.3231 feets²

Explanation:

Given that :

Distance, r = 50 ft

θ = 200°

The arc length of area covered :

Arc length = θ/360° * πr²

Arc length = (200/360) * 50 ft ^2 * π

Arc length = 0.5555555 * 2500 * π

Arc length = 4363.3231 feets²
