A constant retarding force of 20N acts on a body of mass 5 kg moving i

1.	A constant retarding force of 20N acts on a body of mass 5 kg moving initially with aspeed of 10 ms ! How long does the body take to stop?
Answer» Answer: It TAKES 6s for body to stop. since it is retardation then ACCELERATION become NEGATIVE. therefore a= -2.5 m/s^2. It takes 6s for body to stop. I hope it HELPS you don't forget to follow me
