Question

What is the kinetic energy of a running back that has a mass of 95kg and can run 8.5 m/s?

Answer 1

Explanation:

KE = mv2 b. Suppose Karl uses a different puck with. = (85.0 kg)(8.5 m/s) half the mass ... How will. = 3.1X103 J the kinetic energy and work differ from KE; + PE; = KE; + PE those in ... If the puck has half the mass, it still .

Answer 2

Answer:

3431.875 J or 3.432 kJ

Explanation:

Kinetic energy can be found using the equation m/2*v^2.

We know m and v and we can plug in those values to get the answer.

95/2 times 8.5^2 = 3431.875 J or 3.432 kJ.
