Answer:
a) Instantaneous rate at which the force does work on the object = -6 W
b)
Explanation:
a) Given that
and
Instantaneous rate at which the force does work on the object is called power.
Power is the dot product of force and velocity.
Instantaneous rate at which the force does work on the object = -6 W
b) Here given that
Power = -12 W
ANSWER
EXPLANATION
Parameters given:
Mass of car, mc = 1103 kg
Mass of truck, mt = 4919 kg
Initial velocity of car, uc = 18 m/s
Inital velocity of truck = 0 m/s
To solve this problem, we have to apply the law of conservation of momentum, which states that the total momentum of a system is constant.
This implies that:
Since the car and the truck stick together after the collision, they will have the same final velocity.
Hence:
Substitute the given values and solve for v (final velocity):
That is the final velocity of the two-vehicle mass.
