Answer:
7 m/s²
Explanation:
The formula for force is:
We want to find acceleration, so we must rearrange the formula for . Divide both sides of the equation by
Acceleration can be found by dividing the force by the mass.
The force is 42 newtons and the mass is 6 kilograms. A newton is equal to 1 kg * m/s², therefore the force is 42 kg* m/s².
Substitute the values into the formula.
Divide. When we divide, the kg in the numerator and denominator will cancel each other out.
The acceleration of the object is 7 meters per square seconds.
Answer:
0.85 m/s²
Explanation:
Acceleration is change in velocity over change in time. In mathematically, it can be expressed as:
Our final velocity is given to be 17 m/s in 20 seconds. Initial velocity is at starting point which is 0 m/s in 0 second. Therefore:
Therefore, the acceleration of a horse from starting point to 17 m/s in 20 seconds is 0.85 m/s²
