Answer:
The mass of the ball is 5866 g.
Explanation:
Given that,
Impulse = 1.5 N.s
Velocity to the west = 3.8 m/s
Velocity to the east = 4.9 m/s = -4.9 in to the west
We need to calculate the mass of the ball
Using formula of impulse
[tex]I = p_{i}-P_{f}[/tex]
[tex]I=m(v_{i}-v_{f})[/tex]
[tex]m=\dfrac{v_{i}-v_{f}}{I}[/tex]
Where, [tex]v_{i}[/tex] = initial velocity
[tex]v_{f}[/tex] =final velocity
m = mass of ball
Put the value into the formula
[tex]m=\dfrac{3.9-(-4.9)}{1.5}[/tex]
[tex]m=5.866\ kg[/tex]
[tex]m = 5866\ g[/tex]
Hence, The mass of the ball is 5866 g.
