Answer:
They are equal.
Explanation:
Newton's 3rd Law tells is that the forces of an action/reaction pair are equal and opposite. Since F_truck on car and F_car on truck are an action/reaction pair, they are equal no matter their state of movement before the collision.
Acceleration = (change in speed) / (time for the change)
change in speed = (speed at the end) - (speed at the beginning)
change in speed = (37 km/hr) - (89 km/hr) = -52 km/hr
Acceleration = (-52 km/hr) / (6 sec)
Acceleration = (-26/3) km/(hr·sec)
Units: (1/hr·sec) · (hr/3600 sec) = 1 / 3600 sec²
(-26/3) km/(hr·sec) = (-26/3) km/(3600 sec²)
= -26,000/(3 · 3600) m/s²
<em>Acceleration = -2.41 m/s²</em>
Answer:
Zero (0)
Explanation:
A horizontal line will be no movement of negative of positive acceleration
Answer:
It involves all three methods as the handle of the pot is conducting heat via touching the pan which gets it's heat from the burner that is radiating heat to the entire pan through waves of heat from the burner. There is then convection as the heat is being transferred as the liquids temperature changes.
This should be good if I remember it correctly which I hope so much I do.
To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function
Here,
m = mass
a = g = Gravitational acceleration
Replacing we have that the weight is
Since the rope is taut and does not break, the net force on the rope will be zero.
Therefore the tensile force in the rope is 98N
