Answer: 0.37 m/s

Step-by-step explanation:

Given that:

Velocity of object = ?

Mass of object = 17.6 kg

kinetic energy of object = 1.19 J

Since kinetic energy is the energy possessed by a moving object, and it depends on the mass of the object and its velocity, apply the formula

K.E = 1/2 x mass x velocity^2

1.19J = 1/2 x 17.6kg x velocity^2

1.19J = 8.8kg x velocity^2

velocity^2 = 1.19J / 8.8kg

velocity^2 = 0.135

To get the value of velocity, find the square root of 0.135

velocity = √0.135

Velocity = 0.367 m/s (Rounded to the nearest hundredth as 0.37m/s)

Thus, the velocity is 0.37 m/s
