Answer» N:-A hammer of mass 1kg FALLS freely from a height of 20m. Calculate velocity and kinetic ENERGY EXPLANATION:-Let's calculate it's velocityUsing 3rd equation of motion:-So here h(height)=20 mg=9.8 ms²Let's apply thee GIVEN data in the formula to calculate final velocitySo the Velocity of the hammer is =17.79 m SNOW let's calculate it's kinetic energy.Mass of body=1 kgVelocity of body=17.79 m s Hence the kinetic energy of the hammer=158.24 j |
