Compute for the total mechanical energy of a 3.5 kg baseball dropped from a height of 3 meters moving at a speed of 10 m/s. NEED ASAP GRADE 8 SCIENCE TY IN ADVANCE :))

Mechanical energy = Kinetic Energy + Potential Energy

Kinetic energy = 1/2 * m * v² = 1/2 * 3.5 * (10)²

=> Kinetic energy = 175 J

Potential energy = m * g * h = 3.5 * 10 * 3 = 105 J

Hence,

Mechanical energy = Kinetic Energy + Potential Energy

= 175 J + 105 J

= 280 J
