<h2>
Impulse = 4.9 kgm/s</h2>
Explanation:
Impulse is given by change of momentum.
Mass of softball = 0.49 kg
Initial velocity of softball = 13 m/s
Initial momentum = 0.49 x 13 = 6.37 kgm/s
Final velocity of softball = 23 m/s
Final momentum = 0.49 x 23 = 11.27 kgm/s
Change of momentum = Final momentum - Initial momentum
Change of momentum = 11.27 - 6.37
Change of momentum = 4.9 kgm/s
Impulse = Change of momentum
Impulse = 4.9 kgm/s
Answer: potential and kinetic energy.
Explanation: As the book falls, its potential energy is converted to kinetic energy. When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
