Answer:

Force, F = 9 N

Explanation:

The initial velocity of the baseball, u = 0 m/s

Final velocity of the baseball, v = 30 m/s

Time taken, t = 0.5 s

Mass of the baseball, m = 0.15 kg

The force applied by a pitching machine on a baseball can be calculated using the second law of motion. The formula is given by:

$F=ma$

$F=m\times \dfrac{v-u}{t}$

$F=0.15\times \dfrac{30}{0.5}$

F = 9 N

Thus, the pitching machine exerts a force of 9 N on the baseball. This is the required solution.

Answer:

F = 9 N

Explanation:

Acceleration of the ball can be defined as the rate at which the velocity changes

and here we commence with

$a = \frac{dv}{dt}$

noting that

$v_i = 0$

$v_f = 30 m/s$

$\Delta t = 0.5 s$

now we will find

$a = \frac{30 - 0}{0.5} = 60 m/s^2$

to determine the force, we will apply Newton's second law as follows

$F = ma$

from the prior formula we derive

$F = (0.15)(60) = 9 N$

An apple falls from an apple tree growing on a 20° slope. The apple hits the ground with an impact velocity of 16.2 m/s straight

serg [3582]

An apple strikes the ground at a velocity of 16.2 m/s.

The angle between the velocity of the apple and a line normal to the inclined surface is 20 degrees.

The parallel and perpendicular components of its velocity concerning the surface are as follows:

$v_{perpendicular} = v cos20$

$v_{parallel} = v sin20$

This gives us:

$v_{parallel} = 16.2 sin20$

$v_{parallel} = 5.5 m/s$

The velocity along the inclined plane measures 5.5 m/s.

A responder can protect himself/herself from radiation by using shielding as a response action. What materials are best for prot

kicyunya [3294]

Materials that provide effective protection against beta particles include thin aluminum sheets, as well as low atomic mass materials like plastic, wood, water, and acrylic glass for high-energy beta-radiation. These materials can also be used in protective gear, encompassing all clothing designed to shield wearers from radiation-related harm.

13–82. the 8-kg sack slides down the smooth ramp. if it has a speed of 1.5 m> s when y = 0.2 m, determine the normal reaction

Softa [3030]

The second question necessitates a figure to provide an answer. For the initial question
The acceleration of the sack is
1.5² - 0² = 2a(0.2)
a = 5.63 m/s²
The ramp's reaction force is
F = 8 kg (5.63 m/s²)
F = 45 N
Differentiate the kinematic equation with respect to time to find the velocity's rate of increase.
