as per the question charlie runs to the store which is 4 km away
hence the total distance covered [S] is 4 km
he takes 30 minutes to reach the store.
hence the total time taken [t] = 30 minutes=0.5 hour
We have to calculate the average speed.
the average speed[v]=
=
=8 km/hour
then we have to calculate the total distance traveled by charlie in 1 hour.
the distance covered S=
=8 km/hour ×1 hour
=8 km
Hence the average speed of charlie is 8 km/hour and he covers a distance of 8 km in 1 hour.
d final total energy of the systen
Answer:
a large truck that moves fast
Explanation:
look at the question and look how it says (more momentum) which means faster and more force
The person is walking 3.5 miles an hour
Tension may be defined as the pulling power transferred
axially through a cable, string, chain, or alike one-dimensional unceasing object,
or by separately end of a rod.
To compute for tension:
Sum the moments about the pivot:
ΣM = 0 = T * 3.5m * sin37 º - 45000N * 7.0m * cos37º
tension T = 119 434 N
