<span>A. An impulse of a force changes the momentum of a body and has the same units and dimensions as momentum.</span>
Answer:
multiply that and divided by 45
Answer:
The force is 7.8 N.
Explanation:
Given that,
Mass of small object = 2M
Mass of large object = 4M
Here, M = 1.0 kg
Force of the small block = 5.2 N
We need to calculate the acceleration of 4 kg block
Using formula of force




The 2 kg block is also accelerating at 1.3 m/s², making a total of 6 kg.
We need to calculate the force
Using formula of force

Put the value into the formula


Hence, The force is 7.8 N.
40% the formula is work output/work input*100 so
200/500=.4*100=40
