Question

  A man throws a ball of mass 0.4 kg vertically upwards with a velocity of 10 m/s. What will be its initial momentum? What would be its momentum at the highest point of its reach?​

Answer 1

Explanation:

For the final momentum, the final velocity will be zero(0) This is because when the body reaches the highest point then its velocity will be zero and if it had anything more then it should have reached much higher. Then the initial momentum will be, Mass = 0.4 kg. Initial velocity = 10 m/s.

mark me brainliest plz

Answer 2

I want us Cat dp pls(づ｡◕‿‿◕｡)づ

mass*velocity= momentum

when an object is thrown vertically upwards then

final velocity=0

u= 10m/s

so initial momentum=.4*10= 4kgm/s

anddddd

final momentum or momentum at top = ZeRO{cause of v=0}
