Miguel is lifting a 120 kg mass from the floor to a height of 2.50 m during gym class. The gravitational potential energy of the weight when it is lifted is
|
|
30.6 J
|
|
|
3.00 x 102J
|
|
|
4.70 x 102 J
|
|
|
2.94 x 103 J
|
Explanation:
Detailed explanation-1: -Therefore, the potential energy is 75000 J.
Detailed explanation-2: -Answer and Explanation: We must find the work required to lift the mass (w). Therefore, 1372 J of work is required to lift a 70 kg 70 k g mass to a height of 2.0 m .
