A16.0 kg canoe moving to the left at 12.5 m/s makes an elastic head-on collision with a 14.0 kg raft moving to the right at 16.0 m/s. after the collision, the raft moves to the left at 14.4 m/s. disregard any effects of the water. find the velocity of the can

14.1 m/s

Explanation:

given,

mass of canoe, M = 16 Kg

initial speed in left, u = 12.5 m/s

mass of raft. m = 14 Kg

initial speed of raft in right, v = -16 m/s

taking right direction as negative

after collision

speed of raft, v' = 14.4 m/s

speed of canoe,u' = ?

using conservation of momentum

M u + m v = M u' + m v'

16 x 12.5 + 14 x (-16) = 16 x u' + 14 x 14.4

16 u' = -225.6

u' = -14.1 m/s

negative sign represent the velocity is in left direction.

speed of the Canoe after collision is equal to 14.1 m/s

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
