A tennis ball of mass m=0.06kg and speed v=28m/s
strikes a wall at a 45°angle and rebounds with same speed at angle 45° with the impulse given by the wall.​

Respuesta :

Answer:

impulse=1.1879 kgm/s

Step-by-step explanation:

impulse is equal to mass of ball multiply by speed of ball

given, mass of ball=0.06 kg=m

speed of ball=28 m/s=v

speed of ball=28cos45°=19.798

impulse=[tex]0.06\times{19.798}[/tex]

impulse=1.1879 kgm/s  answer
