Answer:
Explanation:
velocity of the Escalators is given as 6 ft/s
now we know that Jane steps on parallel escalator after t = 5 s
so distance moved by John in same time interval is given as
now John and Jane will move towards each other with relative speed
Then will approach towards each other with this relative speed and meet after t = 15 s
so the distance moved by them
so total length of the escalators is given as
Exothermic is the answer to your question

Answer:
Force of friction is 10 N.
Explanation:
Given:
Mass of the table is,
Force acting towards right,
Net acceleration of the table,
Let the force of friction acting on the table to the left be N.
Therefore, net force acting on the table is given as,
Now, as per Newton's second law of motion,
Equating the above two equations, we get
Therefore, the magnitude of the force of friction acting on the table is 10 N to the left direction.
