Question

a Man a person throws A ball of mass 1kg vertically upward with a speed of 5 metre per second what is its momentum at the starting point and at the highest point of its motion​

Answer 1

Answer:

✷GIVEN...

mass (m) = 500g = 500/1000kg = 0.5kg

speed = 10ms^-1

Initial momentum (mu) = ?

momentum at highest point = ?

✷SOLUTION...

Initial momentum = mu

= (0.5)(10)

therefore initial momentum = 5kgms^-1

REMEMBER

the body experiences zero velocity in its highest point.

so there v= 0

Momentum at highest point = m(0) = 0.5 (0)=0

Answer 2

Answer:

Starting:5kgm/s

Highest:0kgm/s

Explanation:

Given;

Mass=1000g=1kg

Speed(v)=5m/s

>Initial momentum :

Momentum=mass*velocity

=1*5

=5 kgm/s

>highest momentum:

Momentum=mass*velocity

=1*0

=0kgm/s

**at the highest point of motion velocity Is 0(zero)
