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.
Answer:
The time taken is
Explanation:
From the question we are told that
The speed is
The length of the tennis court
Generally the time taken is mathematically represented as
=>
