Question

1.)Two objects have masses 8 kg and 25 kg. Which one has more inertia? Why?,,,
2.)What is the momentum of a 6.0 kg ball bowling with a velocity of 22 m/s
3.)Two people push a car for 3 s with a combined net force of 200 N
(a) Calculate the impulse provided to the car.
(b) If the car has a mass of 1200 kg, what will be its change in velocity?
4.)A man of mass 30 kg uses a rope to climb which bears only 450 N. What is the
maximum acceleration with which he can climb safely​

Answer 1

Explanation:

please refer to the attached file

Answer 2

The object with 25 kg mass has more inertia because inertia is directly proportional to mass

Momentum = mass * velocity

= 6*22
=132 kg m/s

Similarly you can solve other questions also
