Explanation:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer:
What is the acceleration of your vehicle?
+ 2.0 m/s^2 ✔
- 2.0 m/s^2
+ 8.0 m/s^2
- 6.0 m/s^2
Answer:
What's the question your asking?
Explanation:
It moves with an initial speed of 25.0 miles per second.
Answer:
Explanation:
A component of 150 N in vertical direction will reduce the magnitude of reaction force.
reaction force exerted by the floor
= mg - 150 sin 30
where m is mass of the crate .
the magnitude of the horizontal component of the 150-newton force
150 cos30
= 130 N
This force tries to pull the crate in forward direction with acceleration but it has no acceleration . It is so because frictional force of equal magnitude acts on it in opposite direction which makes the net force acting on it equal to zero.
Hence frictional force is equal to 150 cos 30.
= 130 N .
Sound energy is produced when an object vibrates so an example would be a telephone ringing or someone playing a bass guitar
