Answer to Question #77092 in Physical Chemistry for merry

Question

a) A particle A of mass 1.5 kg travels in a straight line with a velocity of
3.5 ms-1. Particle A collides with a stationary particle B of mass 2.5 kg.
i) Following the collision, if A and B move away from each other with
a velocity of v m s-1 and 4s m s-1 respectively find the value of V';
ii) Determine if the collision is elastic or inelastic.


b) An object is projected with an initial velocity of 32 m s-1 at an angle of 42° to the horizontal, hitting point B on the same horizontal. Calculate:

i) The time taken for the object to move from point A to point B;
ii) The distance travelled from point A to point B.
