While practising for the snake boat race (Vallum kalli in Kerala), 100 oarsmen are rowing a boat together. Out of these, 95 row backwards to propel the boat forward. But by mistake, 5 oarsmen row in the opposite direction. If each oarsman applies a horizontal force of 200 N, what is the net force on the snake boat? (Ignore drag forces, air friction, etc.)
Each oarsman exerts a horizontal force of 200 N. The 95 oarsmen rowing to push the boat forward provide 95 multiplied by 200 N, equaling 19000 N forward force. The 5 oarsmen rowing backward provide 5 multiplied by 200 N, equaling 1000 N opposing force. The resulting net force on the snake boat is 19Read more

The 5 oarsmen rowing backward provide 5 multiplied by 200 N, equaling 1000 N opposing force. The resulting net force on the snake boat is 19000 N minus 1000 N, which equals 18000 N in the forward direction.

See lessTwo blocks P and Q on a smooth horizontal surface are shown in Fig. 6.36a and Fig. 6.36b. Two forces of magnitudes 4 N and 5 N are acting in opposite directions on block P, while block Q is moving with a constant velocity. Which of the following statement is correct? (i) P experiences a net force and Q does not experience a net force. (ii) P does not experience a net force and Q experiences a net force. (iii) Both P and Q experience a net force. (iv) Neither P nor Q experiences a net force.
Option (i) is the correct statement. Block P is acted upon by two unequal opposing forces of 5 N and 4 N, resulting in an unbalanced net force of 1 N to the right. Block Q travels at a constant velocity with zero acceleration, which according to Newton first law of motion indicates that the net exteRead more
