Question

ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are

measurements.

In working this problem, assume the value of “g” to be 9.8 m/s2 with two (2) significant digits unless

otherwise stated.

A mass of 2700 kg is raised 2.0 m in 10 seconds. What is the potential energy of the mass at this height?

A.39,000

B.3,900

C.0

Answer:52920 Joules

Explanation:This is a case of gravitational potential energy…

We can apply the equation for gravitational energy as P = mgh, where m = mass of object, g = acceleration due to gravity, h = height. Let us substitute the known values into this formula and

solve for P, the potential energy._______________________________________________________

The

massof the object is given to be 2700 kg, raised to aheightof 2.0 meters. The time is not needed in this case, but we know that the acceleration due to gravity is a constant – 9.8 m / s,P = ( 2700 kg )( 9.8 m / s )( 2 m ),

P = 52920

This doesn’t match the given options, so please let me know if you have the right question / options at hand.
