A force of 128 GF act on an object of mass 490 gram for 10 seconds. What velocity it will give to the Mass? |

Answer» The VELOCITY which force gives to MASS = 2612.2 m/s.Given :Force on the mass, F=128\ N.Mass, 490\ g =0.49\ kg.Time period in for which the force is applied, t=10\ s.According to the NEWTON's second law of motion, the force on an object is equal to the mass times times the net acceleration produced in the object, if a is the acceleration of the mass,F=ma\\\Rightarrow a = \dfrac Fm = \dfrac {128}{0.49}=261.22\ m/s^2.Let the mass be starts from rest, so that its initial velocity is u=0\ m/s and its final velocity which the force give be v.Using the equation of Kinematics,v=u+at\\v=0+261.22\times 10=2612.2\ m/s.Explanation:please add me to BRAINLIEST and follow me ✌️✌️❤️ |
