A cyclist and bike have a total mass of 105kg and a speed of 12m/s. Calculate the kinetic energy.

7560J

Explanation:

Given parameters:

Mass of cyclist and bike  = 105kg

Speed  = 12m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy of a body is the energy due to the motion of a body.

 It is mathematically expressed as;

        K.E  = m v²

Insert the parameters:

      K.E  =   x 105 x 12²  = 7560J

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

true tan speed = ang vel x radius
