a book with a mass with 2 kg is placed on a shelf 3 m above the ground calculate the gravitational energy of the book g = 9.8 mass
Answer (1)
PE=mgh =(2kg) (9.8 m/s²) (3m) =(2kg) (96.04m/s2) (3m) =(192.08kg.m/s²) (3m) =576.24J
PE=mgh =(2kg) (9.8 m/s²) (3m) =(2kg) (96.04m/s2) (3m) =(192.08kg.m/s²) (3m) =576.24J
