Question

If the KE of a ball is 200 J and if it has a mass of 1kg, what will be its speed? ​

Answer 1

therefore answer is 20m/s

Answer 2

Answer:

20m/s

Step-by-step explanation:

we know that KE=1/2mv²

given mass=1kg , KE=200J

            200=1/2×1×v²

            400=v²

               v²=400

               v²=(20)²

                 v=20m/s
