Question

3. If the KE of a ball is 200 J and it it has a mass of ikg, what will be its speed:(20m/s)​

Answer 1

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
