Answer:

The answer is 1.98 m/s

Step-by-step explanation:

The velocity of the object can be found by using the formula


v = \sqrt{ (2KE)/(m) } \\

where

m is the mass

KE is the kinetic energy

We have


v = \sqrt{ (2 * 88)/(45) } = \sqrt{ (176)/(45) } \\ = 1.97765292

We have the final answer as

1.98 m/s

Hope this helps you
