Answer:

zero acceleration

Explanation:

Acceleration is defined as the rate change of velocity with respect to time

This means that:

$acceleration = \frac{delta_v_e_l_o_c_i_t_y}{delta_t_i_m_e}$

Now, since the velocity is given as a constant, this means that the value of the velocity does not change which means that the change of velocity is zero.

Substitute in the formula:

$acceleration = \frac{0}{delta_t_i_m_e} = 0$

Therefore, for constant velocity, the acceleration is zero.

Hope this helps :)

Ber [7]

Answer:

Explanation:

A ball is thrown vertically upward with a certain Kinetic Energy in the absence of air resistance and while returning it experiences air resistance.

Air resistance causes the ball to lose its kinetic energy as it provides resistance which will convert some of its kinetic energy to heat energy.

So in a way total energy is conserved but not kinetic energy as some portion of it is lost in the form of heat.

Answer:

1. C

2. D

Explanation:

1. as the object is stationary despite Jamal applying 100N forces, it suggests that the object is applying an equal amount of force on the opposite direction that is opposing the force applied by Jamal.

2. inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

hope it helps. :)

During a baseball game a pitcher threw a baseball, and the catcher, who was behind home plate, caught it. Which is true about th

shtirl [24]

Explanation:

The catcher plays behind home plate in a baseball . The catcher plays an important role in baseball game. He is the main part of the battery with the pitcher. The catcher catches the pitches and help to call the game.

Catcher is the Best Baseball Position.

First Base is the Best Baseball Position.

Second Base is the Best Baseball Position.

Third Base is the Best Baseball Position:

Shortstop is the Best Baseball Position.
