Answer:
the graph would lower down if we are talking about speed because the velocity stops going and theres no more kinetic energy to cause any speed
Explanation:
To solve for the uncertainty of your mass in kilograms,
simply multiply your total mass with the percent uncertainty.
We know that 4% = 0.04, therefore:
uncertainty = 60 kg * 0.04
uncertainty = 2.4 kg
However since uncertainty covers the upper and lower
region, therefore correct answer must be:
<span>± 2.4 kg</span>
Answer:
a).
The magnitude force impulse is
the average force is
Explanation:
Using the conservation energy the potential energy in the high is equal to the kinetic energy just before the collision so:
Notice the mass can be cancel as a factor so:
Now the impulse is determinate by:
The average force is also
