We are given:_________________________________________
Kinetic Energy of object (KE) = 25 Joules
Mass (m) = 34 kg
Solving for the velocity:______________________________________
We know that:
Kinetic Energy = 1/2(mv²)
25 = 1/2(34)(v²) [replacing the variables]
25 = 17(v²)
v² = 25/17 [dividing both sides by 17]
v = √(25/17) [taking square root of both sides]
v = √(25) / √(17)
v = 5 / √17
v = 1.2 m/s
Hence, the speed of the object is 1.2 m/s
