<u>Answer:</u> The mass of the second car is 12666.7 kg
<u>Explanation:</u>
To calculate the mass of car, we use the equation of law of conservation of momentum, which is:
where,
= mass of car 1 = 9500 kg
= Initial velocity of car 1 = 14 m/s
= mass of car 2 = ? kg
= Initial velocity of car 2 = 0 m/s
= Final velocity = 6.0 m/s
Putting values in above equation, we get:
Hence, the mass of the second car is 12666.7 kg
Answer:
The pressure of the box on the floor is 200 Pa
Explanation:
Given,
Length of the box=0.5m
Width of the box= 0.1m
∴Area of the box, A= (0.5 X 0.1) sq.m
= 0.05 sq.m
We know,
Pressure, P= F/A
= 10/0.05 Pa
= 200 Pa
∴The pressure of the box on the floor is 200 Pa
