A dump truck and a little toy matchbox car have the same velocity. which one has the greater momentum?

1 answer:

4 0

That would be the dump truck. Momentum depends on how heavy a certain object is in motion. The more weight it has the harder it is to stop.

Find the x-components of this vector: 92.5 m, 32.0 degrees. Remember, angles are measured from the +x axis.

Brrunno [24]

Answer: $78.44\ m$

Explanation:

Given

magnitude of vector $=92.5\ m$

vector makes an angle of $\theta =32^{\circ}$ with x-axis

Vector can be resolved into two components i.e. vertical and horizontal

Horizontal component along x-axis $=92.5\cos 32$

$=78.44\ m$

along the negative x-axis

If two objects have the same mass, what determines the strength of the gravitational force between them? (4 points) Select one:

Evgen [1.6K]

According to this equation

F = G × m₁*m₂ ÷ r²

other than the mass, the distance also affects the gravitational force between two objects (same mass or not).

Therefore the correct answer is B. The distance between the objects

Future note* use formulas to help you figure these sort of questions out. (if they have a formula to begin with).

The maximum force that a grocery bag can withstand without ripping is 250 n. Suppose that the bag is filled with 20 kg of grocer

zhannawk [14.2K]

Answer:

Groceries stay in the bag.

Explanation:

Given:

Maximum force = 250 N

Bag filled with = 20 kg

Lifted acceleration = $5.0\ m/s^2$

Solution:

We need to calculate the exerted force on the grocery bag by using Newton's second law.

$F = ma$

Where:

F = Exerted force on the object.

m = Mass of the object in kg

a = Acceleration of the object in $m/s^2$

Now, we substitute m = 20 kg and a = $5.0\ m/s^2$ in Newton's second law,

$F = 20\times 5.0$

$F = 100\ m/s^2$

Since, the exerted force on the bag is less than 250 N, the groceries will stay in the bag.
