Momentum = (mass) x (velocity)

Since we have no information about the object's direction,
the best we can do is use the magnitude of its momentum
and find it's speed.

Magnitude of Momentum = (mass) x (speed)

For this object,             (75 kg-m/s) = (3 kg) x (speed)

Divide each side by (3kg):

(75 kg-m/s) / (3 kg)  =  Speed

Speed  =  25 m/s .

Question
A 55 newton force applied on an object moves the object 10 meters in the same direction as the force. What is the value of work done on the object?
Solution 1

Answer: The work done on the object is 110 W

Explanation:

Work is defined as the force that is causing the movement or displacement of an object.

Mathematically,

where,

W = work done on the object

F = Force applied on the object = 55 N

d = displacement = 10 m

Putting values in above equation, we get:

Hence, the work done on the object is 110 W

Question
A wave is moving at the rate of 40 cm/s. Its wavelength is 8 cm. What is the frequency of the wave?
Solution 1
v=40 cms speed of wave

λ=8 cm wavelength

f=? frequency of wave

v=λ⋅f

40=8⋅f

f=408

f=5 s1  is the answer
Question
What does this graph show about the relationship between mass and acceleration? As acceleration increases, mass increases. As acceleration increases, mass is unaffected. As mass is unaffected, acceleration decreases. As mass increases, acceleration decreases.
Solution 1
Describe the relationship between net force and acceleration when mass is held constant. The relationship is directly proportional. This means when net force increases so does acceleration. ... B. Graph the line of Fn (net force) and A (acceleration).
Solution 2
D. as mass increases, acceleration decreases.
Question
Sully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. The total mass of the snowmobile, including Sully, is 280 kilograms. If Sully accelerates to a velocity of 16 meters/second over 10 seconds, what’s the force exerted by the snowmobile to accelerate? Use F = ma, where . 160 N 168 N 248 N 280 N 324 N
Solution 1
16 - 10 = 6
6 / 10 = .6 (this sign / means to divide)
F = 280 x .6 = 168
Solution 2

16 - 10 = 6
6 / 10 = .6
F = 280 x .6 = 168

Question
Does the moon really change shape? Explain.
Solution 1
Wouldn't say it changes shape but it does look like it does but its because the moon spins around the sun which makes it turn to full moon, half moon, crescents but it is still a circle its just that the sun shapes it by the rotation.
Question
According to Charles's Law, if the pressure of a gas stays constant, when the temperature increases, the volume __________.
Solution 1
The correct answer is "the volume increases".

In fact, Charle's law states that when the pressure of a gas stays constant, the ratio between the temperature and the volume of the gas is constant:

where T is the gas temperature and V is its volume. We see from the formula that, if the temperature T increases, since the ratio must remain constant, the volume of the gas V increases as well.
Solution 2

The volume increases is right for apex
