A bullet fired from a riffle travels at an average speed of 2880 km/h. It hits the target after 0.1 seconds. How far (in metre) is the target from the riffle? Correct Answer 80

Given:

Average speed of a bullet which is fired from the riffle = 2880 km/h

Formula used:

Distance = speed × time

Concept used:

m/s = (km/h) × (5/18)

Calculations:

Speed in m/s = 2880 × (5/18) = 800 m/s

Distance = 800 × 0.1 = 80 m

∴ The distance travel by the bullet to hit the target is 80 m.

Statement I When a gun is fired, i.e. it placing pushes back with much less velocity than the velocity of the bullet.
Statement II Velocity of the recoiling gun is less because the gun is much heavier than bullet.
According to the Principle of conservation of momentum when the gun is fired, momentum of gun and bullet system remains constant.
What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.
