Question

Answer...... This question... Please....

Answer 1

•Initial momentum is equal to
mass*initial velocity of the object
10*50/1000 = 0.5kgm/s
•final momentum is equal to
mass*final velocity of the object
10*70/1000 = 0.7kgm/s
•rate of change of momentum
Final momentum-initial momentum
0.7-0.5/2 = 0.1 kgm/s^2
•acceleration of the ball is equal to
70-50/2 = 10m/s^2
•change in momentum is equal to force thus force is equal to 0.1N
