A ball of mass 0.7 kg flies through the air at low speed, so that air resistance is negligible. (a) What is the net force acting

Fed [463]

Answer:

A) Gravitational Force, $F=-6.86N$ .

B) The y component of momentum.

C) The x component of momentum will remain the same.

D)The y component of momentum decreases.

E)The z component of momentum will remain constant.

Explanation:

First, let the x-axis be positive in the same direction as the horizontal speed of the ball, let the y-axis be positive in the opposite direction of gravity.

A) since there is no air resistance, the only force acting on the ball is the gravitational force. This force is downwards so it is negative. The net force is

$F=-9.8*0.7=-6.86N$ .

B)Because the net force (and the only one) is on the y-axis, only the vertical component of the momentum will be changed due to the force.

C)Since there is no resistance of air, the ball behaves as in projectile motion problems, this means that the x component of the velocity remains constant, also does the mass. Remembering that momentum is velocity times mass, it can be easily seen that x component of momentum remains constant too.

D)The y component of momentum decreases, this is because gravity decreases the y component of the velocity.

E)Since there is no z component of the force there is no change in the z component of the momentum.

a bicyclist initially at rest speeds up steadily during this time interval she averages 3.50 miles per second determine the init

Kobotan [32]

Answer:

Explanation:

Given parameters:

Average speed = 3.5miles per second

Unknown:

Initial speed = ?

Average speed = ?

Final speed in the interval = ?

Solution:

Since the bicyclist started from rest and speeds up steadily, it is correct to assume that her starting or initial speed is 0m/s.

At a state of rest, a body has no speed.

Average speed is the sum total of the speed covered at each time interval. This value is given already to be 3.5miles per second.

Final speed is the speed before the bicycle halts. This speed will be the same as the average speed here which is 3.5miles per second.

Speed is the rate of change of distance with time.

An arrow in flight has an initial velocity of 65 meters per second, and 10 seconds later, it has a velocity of 35 meters per sec

Sergeu [11.5K]

To find the acceleration, we would need to use the equation acceleration= final velocity- initial velocity/elapsed time. Since the final velocity is 35 and the initial velocity is 65, we can subtract 65 from 35 first, which gives us -30. Then if we divide that by the elapsed time, which is 10, we get -3. Your acceleration is -3 meters per second.

Hope this helps! :D

If a current of 2 amps is moving through a circuit connected to a 12 V battery, what is the resistance of the circuit?

Gnoma [55]

The resistance of the circuit, when current is moving through it, is 6 ohm.

<h3>What is current?</h3>

The current is the stream of charges which flow inside the conductors when connected across the end of voltage.

If a current of 2 amps is moving through a circuit connected to a 12 V battery.

So, I = 2A and V= 12 V

From the Ohm's law, V =IR

R = V/I

By substituting the values, we get

R = 12/2

R 6 ohms

Thus, the resistance of the circuit is 6 ohm.
