A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 43.0 m/s; when it leav

kotykmax [81]

Answer:

$-7.352\times 10^3$ N

Explanation:

We are given that

Mass of baseball=m=0.145 kg

Initial velocity of ball=u=43 m/s

$\theta=31^{\circ}$

Speed, v= $51 m/s$

Time, t=1.71 ms= $1.71\times 10^{-3} s$

$1 ms=1.71\times 10^{-3} s$

Horizontal component of the average force on the ball= $\frac{m(vcos\theta-u)}{t}$

Horizontal component of the average force on the ball $=\frac{0.145(-51cos31-43)}{1.71\times 10^{-3}}$

Horizontal component of the average force on the ball= $-7.352\times 10^3$ N

Two wheels initially at rest roll the same distance without slipping down identical planes. Wheel B has twice the radius, but th

OlgaM077 [116]

Answer:

Their translational kinetic energies are the same

Explanation:

The translational kinetic energy of an object is given by the formula:

$KE = 0.5 mv^2$

Where m = the mass of the object and

v = the linear speed of the object

From the question, it is stated that wheel A has the same mass as wheel B, that is $m_A = m_B$

Linear speed is also a function of the distance covered. Since both wheels cover the same distance within the same interval, we can conclude that $v_A = v_B$

Both wheels A and B have equal speed and mass, this means that their translational kinetic energy is the same.

Note that translational kinetic energy is not a function of the radius

What do we call the average motion of moving atoms and molecules in the atmosphere?

jonny [76]

Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object.
