Question

An object of mass 2 kg is placed at rest in a frame (S1

) moving with velocity j

ˆ

i 5

ˆ 10  m/s and having

acceleration j

ˆ

i 10 ˆ 5  m/s2 . This object is also seen by an observer standing in a frame (S2

) moving

with velocity j

ˆ

i 10 ˆ 5  m/s.

(i) Calculate ‘Pseudo force’ acting on object. Which frame is responsible for this force.

(ii) Calculate net force acting on object with respect to S2

frame.

(iii) Calculate net force acting on object with respect to S1

frame.​
