Answer:3.25914099112
Explanation:
Do you have the formula? I pretty sure this is correct but I’m not sure
Speed of ball is 3.2 m/s (Approx.)
Given that;
Kinetic energy (KE) = 17 J
Mechanical energy = 25 J
Mass of ball = 3.2 kg
Find:
Speed of ball
Computation:
Kinetic energy (KE) = [1/2][mv²]
17 = [1/2][(3.2)v²]
17 = [1.6][v²]
v² = 17 / 1.6
v² = 10.625
v = √10.625
v = 3.2596
Speed of ball (v) = 3.2 m/s (Approx.)
