Solution :
Given the laser light which is sent through the double slit produces an interference pattern on the screen placed 3 meters from the slits.
The 8th order maximum occurs at angle = 12
So,
, m = 8
Answer:
Velocity of truck is 21.875 m/s.
Explanation:
Given:
Mass of the car (m) = 2500 kg
Initial speed of the car (u) = 35 m/s
Mass of the truck (M) = 4000 kg
Initial speed of the truck (U) = 0 m/s (Rest)
As per question, the total momentum of the car gets transferred to the truck.
Therefore, the final momentum of the car is 0.
Momentum is given as the product of mass and velocity.
So, if momentum becomes zero means the velocity becomes 0.
Therefore, final velocity of the car (v) = 0 m/s
Let the final velocity of truck be 'V' m/s.
Now, during collision, the total momentum remains conserved.
Initial momentum = Final momentum.
Initial momentum of car + Initial momentum of truck = Final momentum of car + Final momentum of truck.
⇒
Therefore, the velocity of the truck is 21.875 m/s.
