Answer:
It is neither false nor true. When they collide some of one of the objects goes to the other object.
Explanation:
Answer:
(A) 0.3488 rad/sec
(B) 124.246 m
Explanation:
We have given car completes one revolution in 18 sec'
So time period T= 18 sec
Tangential speed v = 43.4 m/sec
(A) Angular velocity is given by 
(B) Tangential velocity is given v = 43.4 m /sec

Answer:
it is due to the elastic rubber and the air pressure builds up and the rubber expands
The correct answer to the question is 2.27
i.e the acceleration of the body is 2.27
along the forward direction.
CALCULATION:
As per the question, the net external force on the propeller of model airplane F = 6.8 N.
The mass of the model air plane m = 3.0 kg
We are asked to calculate the acceleration of the air plane.
From Newton's second law of motion, we know that the net external force acting on a body is equal to the product of mass with acceleration of that body.
Mathematically force F = m × a
⇒ 

[ans]
The direction of acceleration is along the direction of force. Hence, the acceleration of the propeller is 2.27
along forward direction.
