What type of force cause an object to accelerate??

Physics
1 answer:
Olin [163]3 years ago
8 0
ANY force causes an object to accelerate, just as long as there are not
some other forces on the object that cancel out the first one.

Are you looking for the answer ... an "UNBALANCED" force ?
That's a very poor way to describe it, because there's no such thing
as a balanced or unbalanced force.  The thing that's balanced or
unbalanced is a GROUP of forces, not a single force.

How can a heavy moving van have the same momentum as a small motorcycle?
vladimir1956 [14]
Hello there!

The formula for momentum is p=mv.
p is momentum, m is mass, and v is velocity.

The mass of a heavy moving van will be much greater than the mass of a motorcycle, so how can they have the same momentum?

They can have the same momentum if the velocity of the moving van is less than the velocity of the motorcycle, or if the velocity of the motorcycle is greater than the moving van (same thing but differently worded)

Let the mass of the moving van be greater than the mass of the motorcycle by a factor of k. In order for the two to have the same momentum, the velocity of the motorcycle must be greater than the velocity of the moving van by the same factor, k.

Hope this helps! :)

A uniform 4.4 t magnetic field points north. if an electron moves vertically downward (toward the ground) with a speed of 2.5 ×
Reil [10]

Answer:

1.8\cdot 10^{-11} N

Explanation:

The force acting on the electron due to the magnetic field is

F=qvB sin \theta

where

q=1.6\cdot 10^{-19} C is the charge of the electron

v=2.5\cdot 10^7 m/s is its speed

B=4.4 T is the intensity of the magnetic field

\theta=90^{\circ} is the angle between the direction of the field and the velocity of the electron

Substituting all the numbers into the equation, we find

F=(1.6\cdot 10^{-19}C)(2.5\cdot 10^7 m/s)(4.4 T) sin 90^{\circ}=1.8\cdot 10^{-11} N

sergij07 [2.7K]

Answer:

He calculated his average speed.

Explanation:

Waldo calculated an average of his speed in 2 hours rather than his speed whilst driving which means instead of doing 50/1 hour = 50 mph, he did 50/2hours which is how he got 25 mph. Hope this helps!
