Answer:
6 m/s²
Explanation:
We know that the force acting on an object varies directly with the acceleration. The force, F, and acceleration, a, are related by:
F = m * a
Where m is the mass of the object
We then need to find the mass of the object before we can find its acceleration when the force is 30 m/s².
Therefore, when the force is 20 N and the acceleration is 4 m/s²:
20 = m * 4
=> m = 20/4 = 5 kg
The mass of the object is 5 kg. Hence, we can find the acceleration of the object when the force is 30 N
30 = 5 * a
=> a = 30/5 = 6 m/s²
The acceleration of the object is 6 m/s²
Answer:
6m/s²
Explanation:
According to Newton's second law
Force F acting on an object varies directly with the object's acceleration a. Mathematically it is expressed as
F = ma where;
m is the mass of the object
F is the applied force
a is the acceleration
Let m be constant
m = F/a
If a force of 20 N acts on a certain object with an acceleration of 4m/s²
m = 20/4
m = 5kg
If the force is changed to 30 N, its new acceleration can be gotten using the previous formula.
F = ma
a = F/m
a = 30/5 (since mass is kept constant)
a = 6m/s²
