Explanation:
Let 'F' be force acting perpendicularly, 'A' be the area and 'P' be the pressure exerted.
Then,
Pressure is directly proportional to the the force acting perpendicularly i.e.
P ∝ F ............. (i)
Pressure is inversely proportional to the area on which force acts i.e.
P ∝ 1/A ........... (ii)
Combining equations (i) and (ii),
P ∝ F/A
or, P = K × F/A [where K is a constant]
If F is 1N, A is 1m² and P is 1 N/m², then K is 1.
So, P = F/A proved...
Answer:4500 N
Explanation:
Given
mass of truck 
mass of car
as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck
and their acceleration is
Answer:
60 m/s (in the opposite direction)
Explanation:
By conservation of momentum,
Initial momentum of board + Initial momentum of man = Final momentum of board + Final momentum of man
=> 0 + 40*12 = 8*(-v) + 0
=> v = -60 [ Negative indicates opposite direction ]
