Answer:
<em>v=40 m/s south</em>
Explanation:
<u>Momentum
</u>
It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg.m/s and the formula is

Where m is the mass and v the velocity of the particle. If we wanted to solve for v, we have

The baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg, thus

The velocity is directed to the south

KE=1/2 m v^2
KE= .5 x 2kg x 15m/s to the 2nd power
KE=225 km/s
Well first graph represents rectangular hyperbola
vu = c^2 ( c is constant)
AS 1/v + 1/u = 1/f
Take1/ f to be constant c
1/v = c - 1/u
it is of the form y = - x + k
Slope = -1 having intercept k as shown in fig 2
Gravitational forces are forces of attraction. It's like the Earth pulling on you and keeping you on the ground.
