1.
Impulse is defined as
Net force × distance
Force ÷ time
Mass × velocity
Net force × time
2.
A 20 N force acts on an object for 3.0 s. The impulse is
6.7 N·s
60 N·s
23 N·s
17 N·s
3.
Which is a unit of impulse?
J
kg·m/s²
kg·m/s
W
4.
Impulse is
A vector in the direction of the net force
A scalar
Always opposite to the motion
Always zero if there is no displacement
5.
A force of 400 N acts for 0.020 s on a 0.40 kg ball initially at rest. Its final speed is
20 m/s
8.0 m/s
200 m/s
0.50 m/s
6.
The same impulse is given to a 1.0 kg cart and a 4.0 kg cart, both at rest. The ratio of the final speeds (1.0 kg : 4.0 kg) is
1 : 4
1 : 2
4 : 1
2 : 1
