Part 1: The following questions refer to the motion of a baseball. Call towards home plate positive and towards the outfield neg
mr Goodwill [35]
<span>These are three questions and three answers

1. Question 1.


Part 1:

Answer: 5 N*s

Explanation:

Data:

F = 125 N
m = 141 g = 0.141 kg
t = 0.04 s

Δp =?

2) Formula

Impulse = F.t =

Impulse = Δp

3) Solution:

=> Δp => F.t

Δp = 125 N * 0.04 s = 5 N.m


2) Question 2

Part 2
: If the initial speed of the baseball is v = 0.0 m/s, what will its speed be when it leaves the pitcher's hand?

Answer: 35.5 m/s positive (toward the homelate)

Explanation:

1) Data:
vi = 0.0 m/s
vf = ?

2) Formula

Δp = mΔv

3) Solution:

Δv = Δp / m

Δv = 5 N*s / 0.141 kg = 35.5 m/s

Δv = vf - vi => vf = Δv + vi = 35.5 m/s + 0 = 35.5 m/s, positive because it is toward the homeplate.

3) Question 3

Part 3: When the batter hits the ball, a net force of 1165 N, opposite to the direction of the ball's initial motion, acts on the ball for 0.005 s during the hit. What is the final velocity of the ball?

Answer: - 76.8 m/s (negative because it is towards the field)

Explanation:

1) Data:

F = 1165 N
t = 0.005 s
vf = ?

2) Formulas

I = f.t

I = Δp

Δp = mΔv

3) Solution

I = F.t = 1165 N * 0.005s = 5,825 N*s

Δp = I = 5,825 N*s

Δp = mΔv => Δv = Δp / m = 5,825 N*s / 0.141 kg = 41.3 m/s (negative because it is towards the field)

Δv = vf - vi => vf = Δv + vi = - 41.3 m/s - 35.5 m/s = - 76.8 m/s

one car travels east for 360 m over a period of 15 seconds. a second car travels west for 120 m over a period of 5 seconds. what
lesya692 [45]
Take it one step at a time.

-- Remember that 'speed' means (distance) divided by (time),
and the direction doesn't matter.

-- Remember that 'velocity' means the speed and the direction.

<em>First car:</em>
360 meters east in 15 sec.
Speed = 360/15 = 24 meters per second
Velocity = 24 meters per second east

<em>Second car:</em>
120 meters west in 5 seconds
Speed = 120/5 = 24 meters per second
Velocity = 24 meters per second west

-- Their speeds (24 and 24) are equal.

-- Their velocities are equal magnitude but opposite (24 east / 24 west).
