Examination 2021
Two bodies A and B of masses 100g and 400g respectively are moving
towards each other with a speeds 100cm/s and 10cm/s.
They suffer a
head-on collision and stick together.
(i) In which direction will the combined mass move after the collision?
(02 marks)
(ii) What will be the distance travelled by the combined mass after 10
seconds.
(01 marks)
(iii) Assuming the two bodies to be originally at the same temperature and
specific heat of both the two bodies to be 0.1Jg-'K-1, calculate the rise
in temperature of the combined mass after the collision. (02 marks)
