Answer:
Explanation:
Given
Diver is at a depth of inside the water
As we go down pressure increases due to the weight of liquid column above us
Pressure difference is given by
Where =density of liquid
h=depth
g=acceleration due to gravity
So external-internal pressure difference is
Answer:
The unknown mass of the bullet is
Explanation:
According to Newton's laws of motion, when a net external force acts on a body of mass <u><em>m</em></u> , it results in change in momentum of the body and is given by:
Where:
P
is the linear momentum of the body
As a consequence, when there are no external forces acting on the body the total momentum remains conserved i.e.
Given:
For momentum along the y-direction to be zero, it is achieved when the equal masses are moving at angles of
θ1=180°, θ2=60°, θ3=-60°
Therefore, from conservation of momentum along x - direction:
Answer:
The average acceleration is
Explanation:
<u>Uniform Acceleration </u>
When an object varies its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The acceleration can be calculated by solving for a:
The Indy 500 race car increases its speed from vo=4 m/s to vf=36 m/s in t=4 s. Thus, the average acceleration is:
The average acceleration is
