If a 2.2-kg ball is thrown with a velocity of 10m/s what is its KE

The answer is 110 Joules

Step-by-step explanation:

Kinetic energy ( KE) of an object is given by

where

m is the mass

v is the velocity

From the question

m = 2.2 kg

v = 10 m/s

Substitute these values into the above formula

That's

We have the final answer as

Kinetic energy = 110 Joules

Hope this helps you

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
