A small coin is placed on a horizontal turn table. The turn table is observed to make three revolutions in 3.14 sec. What is the coefficient of static friction between the coin and turn table if the coin is observed to slide off the turn table when it is greater than 10 cm from the centre of the turn table  
  • a)
    0.4  
  • b)
    0.04  
  • c)
    4    
  • d)
    0.004

F = ma
so a = 250/30 
a = 8.34
now the result is 4mt/secsqure
so reduction is 4.34
friction force will b 4.34 ×30 
 F = 130.2 N

The force exerted by the cyclist is equal to the mass of the cyclist multiplied by his acceleration. Therefore, the force exerted by the cyclist is:

Force = mass x acceleration
Force = 30 kg x 4 m/s^2
Force = 120 N

Since the cyclist is exerting a force of 250 N to move the cycle, there must be some additional force acting on the cycle. This additional force is the force of friction or resistance. The force of friction can be calculated by subtracting the force exerted by the cyclist from the total force:

Frictional force = Total force - Force exerted by cyclist
Frictional force = 250 N - 120 N
Frictional force = 130 N

Therefore, the force of friction or resistance acting on the cycle is 130 N.
