Question

Manoj was travelling by Metro train while Rajnish was travelling by his car towards the same destination. Manoj was surprised to reach much before Rajnish and said, since his motion was uniform, he could reach on time. However, Rajnish said that Manoj’s motion was also not uniform. 

(i) Who gave a correct explanation of types of motion? 

(ii) How did Manoj reach early? 

(iii) Give the characteristic values of Manoj.

Answer 1

(i) Rajnish gave the correct explanation as for a uniform motion the velocity should be uniform. But the metro has stopped at various stations which means that it had come to rest and its velocity at that point is zero. 

(ii) Manoj had used metro which is free from the traffic jam and thus manages to reach early. 

(iii) Manoj is a responsible citizen as he had used a public transport instead of the personal car which helps in conservation of fuel.
