Answer:
Explanation:
As we know that the mass of the fleas is given as
now the speed of the fleas is given as
now just before it will jump let say it has some energy E
so as per energy conservation law we can say that this total initial energy will convert into its kinetic energy just after the jump
so the initial total energy is given as
Answer:
<em>Answer: Work equals force times distance. 3,000 J</em>
Explanation:
Work Done By A Force
When some force is applied and a displacement is achieved, the work done by the force is given by
Note that the work is a scalar magnitude as the result of the dot-product of two vectors. If the force and the displacement are parallel, then the vectors can be replaced as its magnitudes F,x and the work is
The dot product becomes a simple arithmetic product, i.e force times distance.
Sara weighs 500 Nw and she climbs up a 6 meter set of stairs. She needs to lift her weight up, so the force is the weight and the distance is the height of the stairs, thus
Answer: Work equals force times distance. 3,000 J
