Abat hits a moving baseball. if the bat delivers a net eastward impulse of 1.5 n-s and the ball starts with an initial horizontal velocity of 3.8 m/s to the west and leaves with a 4.9 m/s velocity to the east, what is the mass of the ball (in grams)? (never include units in the answer to a numerical question.)

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

Where, = initial velocity

=final velocity

m = mass of ball

Put the value into the formula

Hence, The mass of the ball is 5866 g.

answer; /// the above statement is (true);

the bal will not change its velocity.
