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.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
