A newspaper seller is riding a bicycle with a pile of newspaper in his basket. He drops the newspaper in the entrance of every house as he passes by without slowing down his cycle. He passes house 203 with a velocity 42m/s and constant acceleration and reaches house 204 in 16 sec. From house 204, he continues travelling with triple the acceleration and reaches house 205 at a velocity 63m/s in 4 sec. What is the velocity of the newspaper seller at house 204?

Answer:
A newspaper delivery boy is riding his bicycle down the street at 5.0 m/s. He can throw a paper at a speed of 8.0 m/s. What is the paper’s speed relative to the ground if he throws the paper (a) forward, (b) backward, and (c) to the side?
Step-by-step solution:
Step 1 of 5
Relative velocity is about the frame of reference of measurement. For the newspaper boy moving on a cycle is motion frame and the ground is the reference frame. If S is the reference frame (ground frame) then is the motion frame moving with respect to the reference frame. The Galilean transformation of velocity of the cyclist with respect to the ground frame for one dimension is
Here, is the speed of the newspaper and is the speed of the motion frame (cyclist). The direction of the motion frame decides the sign of in the above equation. If the motion frame and motion of the newspaper is along same direction then the sign is positive else negative
