Given:
Mass = 4.0 kg
Kinetic energy = 50 J
Determine the speed of the bowling ball.
Formula for the Kinetic Energy:
Ke = ½ mv^2
v = (2Ke/m)^½
Solution:
Substitute the given values of Ke and m to the formula for v in terms of Ke.
v = (2Ke/m)^½
v = (2(50)/(4))^½
v =(100/4)^½
v = (20)^½
v = 4.47 m/s
Final answer:
v = 4.47 m/s
