Aheavy 2.0kg ball is moving at 10m/s when it is caught. a light 1.5kilogram ball is travelling at 20m/s when it caught. which ball required the greater impulse? a) the 2.0kg ball because it is more massive. b) the 2.0kg ball because it had more momentum c) the 1.5kg ball because it was travelling faster d) the 1.5 kg ball because it is more momentum e) the question can’t be answered without more information.

To check impulse you will need more information you will require more data as it was diverse with time. In this question, there are two balls with various mass and speed, along these lines they have diverse force. I will expect you are getting some information about the momentum.

The momentum of ball 1 should be:

momentum 1 = mass₁ x velocity₁

momentum 1 = 2kg x 10m/s = 20kg m/s

The momentum of ball 2 should be:

momentum 2= mass₂ x velocity₂

momentum 2= 1.5kg x 20 m/s = 30kg m/s

The answer would be "1.5kg ball because it was travelling faster".

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
