The kinetic energy of a 10-kilogram object is 2000 joules. What is the speed of the object, in m/s?
Svetllana [295]

Answer:

<u><em>20 m/s.</em></u>

Explanation:

Mass of body m: 10kg

The kinetic energy of the body is given as; K.E= \frac{1}{2} * m * v^{2}

Value of Kinetic energy K.E = 2000 Joules

V is the body's velocity, and M is the body's mass.

Calculating the value of velocity; V=\frac{\sqrt{2K*E} }{m}  V= \frac{\sqrt{2*2000} }{10}  = V=20m/s

Velocity maintained by the body having a kinetic energy of 2000J is

20 m/s.

What is the minimum tangential velocity a space station would need to simulate earth gravity if the radius is 50 meters ?
Aneli [31]

Explanation:

angular velocity is given by

w =  \sqrt{ \frac{g}{r} }

w =  \sqrt{ \frac{9.8}{25} }

w = 0.626

now tangential velocity is

V = rw

= 25 x 0.626

= 15.65 m/s

To impress his friends while riding on a carnival
s344n2d4d5 [400]

Answer:

B. decreases while his angular speed remains  unchanged.

Explanation:

His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
