Answer:
6 m/s²
Explanation:
We are given;
- The mass of the block as 6.2 kg
- Horizontal force as 50.9 N
- Frictional force as 13.7 N
We are required to determine the acceleration of the block.
- According to second Newton's Law of motion; Resultant force is directly proportional to the rate of change in linear momentum.
Therefore;
F = Ma , where F is the resultant force, m is the mass and a is the acceleration.
In this case;
Resultant force, F = Horizontal force - friction force
= 50.9 N - 13.7 N
= 37.2 N
Thus;
37.2 N = 6.2 kg × a
Hence;
acceleration, a = 37.2 N ÷ 6.2 kg
= 6 m/s²
Therefore, the acceleration of the block is 6 m/s²
Answer:
they are the same
Explanation:
change in speed is 10km/h for both, and the time is the same for both. they have the same acceleration.
Option 3) a Soccer Ball
will travel the farthest distance.
Answer:
a. xy
Explanation:
The Faraday's law of induction can be used to express the relationship between the electric field line integral and the magnetic flux rate change in a closed loop. In order to ensure that the relationship between the two variables is equivalent to zero, the integration should be conducted on the xy plane. The correct option is option a.
