Answer:
v=9.6 km/s
Explanation:
Given that
The mass of the car = m
The mass of the truck = 4 m
The velocity of the truck ,u= 12 km/s
The final velocity when they stick = v
If there is no any external force on the system then the total linear momentum of the system will be conserve.
Pi = Pf
m x 0 + 4 m x 12 = (m + 4 m) x v
0 + 48 m = 5 m v
5 v = 48
v=9.6 km/s
Therefore the final velocity will be 9.6 km/s.
Answer:
F = 3.15 N
Explanation:
Given electric charge, q = 6.3 μC
The magnitude of electric field,
We need to find the electric force on the charge due to the electric field. The electric force is given by :
F = qE
Putting all the values,
So, the required force on the charge is 3.15 N.
The steps of the use of the laser technique is explained below:
- A laser beam is emitted from the diode in the unit and spread into a laser plane (1).
- The laser plane, appearing as a line on the sphere (2), is reflected and collected by dual CCD arrays (1).
- The resulting 2D profile is digitized and as the unit travels along the x-axis of the object, multiple profiles are collected yielding a 3D coordinate point cloud of the surface (3).
This refers to the type of surgery that makes use of special light beams in order to cut open the human body in a surgical procedure.
Hence, we can see that the laser technique is considered safer than conventional surgical methods.
Laser techniques include:
- laser vaporization,
- laser resection-enucleation,
- coagulation.

The acceleration due to the stopping force of the brakes is given by Force/mass = 1000/3568 =.28m/s^-2
We will apply the equations of motion to calculate the braking distance.
; where V is the final velocity, U is the initial velocity, a is the acceleration and s is the displacement.
0=43^2-2(0.28)*s
Solve for s.
