Answer:
1.30 m
Explanation:
The pressure (P) exerted by a column of a liquid can be calculated with the following expression:

where,
ρ is the density of the liquid
g is the gravity
h is the height of the column
If both liquids exert the same pressure:

Kinetic energy = (1/2) (mass) (speed squared)
Kinetic energy = (1/2) (400 kg) (17 m/s)²
Kinetic energy = (1/2) (400 kg) (289 m²/s²)
<em>Kinetic energy = 57,800 Joules</em>

Given
The y-component of vector K is

The magnitude of vector K is , K=8 cm
To find
The angle

Explanation
Resolving K along its y-component we have,

Conclusion
The angle made with the x-axis is
Answer:
Distance traveled during this acceleration will be 6950 m
Explanation:
Wear have given maximum speed tat will be equal to final speed of the car v = 278 m/sec
Constant acceleration 
As the car starts initially starts from rest so initial velocity of the car u = 0 m/sec
From third equation of motion 
Putting all values in equation

s = 6950 m
So distance traveled during this acceleration will be 6950 m
