A player at first base catches a throw traveling 38 m/s. The baseball, which has a mass of 0.145 kg, comes to a complete stop in

the glove after 0.14 s. Assuming the force of the glove was uniform, what force did the glove exert on the ball?

Answer:

F = 39.36 N

Explanation:

given,

initial speed, u = 38 m/s

final speed, v = 0 m/s

mass of ball = 0.145 Kg

time, t = 0.14 s

Force = ?

using impulse formula

J = change in momentum

J = F x t

m(v - u) = F x t

0.145 x (0 - (-38)) = F x 0.14

F x 0.14 = 5.51

F = 39.36 N

force exerted by the ball is equal to 39.36 N.

Torque can be best described as which of the following? Give an example of both a force and a torque and explain why in a couple
kicyunya [14]

Answer: rotational force

Explanation:

Torque is the twisting force which cause rotation and the axis of rotation is the point at which the object rotates.

Torque is a rotational force as it leads to the rotation of an object about an axis. Force simply means a pull or push. When an unbalanced ball acts on a force, the ball, the ball will be moved towards the linear motion.

Then, the unbalanced force that is acting in the ball produces torque which causes the ball's rotational motion.

You're having a hard time pushing a refrigerator across the kitchen floor. The force of your own push is 993 N. The force of fri
Helen [10]

Answer:

The acceleration of the refrigerator is a= 0.056 ms^{-2}

Explanation:

The expression of the equation of the net force acting on the refrigerator is as follows;

F-f= ma

Here, F is the applied force, f is the force of friction, m is the mass and a is the acceleration.

It is given in the problem that you're having a hard time pushing a refrigerator having mass 355 kg across the kitchen floor. The force of your own push is 993 N. The force of friction opposing your own push is 973 N.

Put F= 993, f= 973 N and m = 355 kg in the above expression of the equation to calculate the acceleration of the refrigerator.

993 - 973 = (355)a

20 = 355 a

a= 0.056 ms^{-2}

Therefore, the acceleration of the refrigerator is a= 0.056 ms^{-2}.

What are limitations of the calculated and indirect volume measurement?
tresset_1 [31]

Answer: The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measures the displacement of a liquid by a solid.

Explanation:

Volume is the amount of  the space occupied by an object. Volume can be used to measure the amount of the space occupied by the solid, liquid and gas.

When the direct measurement is not possible then the indirect measurement is used by taking the small part that object to calculate the whole part of that.  

The limitations of the calculated and indirect volume measurement are as follows,

The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measure the displacement of a liquid by a solid. For example, the volume of the liquid is displaced by the sponge is not equal to the volume of the sponge.
