Answer
The driver should reduce the speed or velocity of vehicle
because momentum which is
Mass x velocity will be reduced if velocity reduces and reduce force if impact
Thermal energy is not in the process of being transferred it is not in transit but remains as part of the internal energy of the system heat on the other hand is energy in transit energy is the process of being transferred from a hotter system towards another colder system
Answer:
Fc = 89.67N
Explanation:
Since the rope is unstretchable, the total length will always be 34m.
From the attached diagram, you can see that we can calculate the new separation distance from the tree and the stucked car H as follows:
L1+L2=34m
Replacing this value in the previous equation:
Solving for H:
We can now, calculate the angle between L1 and the 2m segment:
If we make a sum of forces in the midpoint of the rope we get:
where T is the tension on the rope and F is the exerted force of 87N.
Solving for T, we get the tension on the rope which is equal to the force exerted on the car:
Answer:
E 6.0sin132 = 4.46 km East
N 6.0cos132 = - 4.01 km = 4.01 km South
