Answer:
Acceleration, a = 0.5m/s²
Explanation:
Given the following data;
Force, f = 20N
Mass = 40kg
To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation;
Acceleration, a = 0.5m/s²
Therefore, the acceleration of the bookcase is 0.5m/s²
Answer:
Velocity has a direction associated with it, while speed has no specific direction.
Explanation:
Velocity is a vector, while speed is a scalar.
False.
The force of friction is always the direction opposite of the object's movement.
Buoyancy from water. Buoyancy is an upward force on an object immersed in a fluid (i.e., a liquid or a gas), enabling it to float or at least to appear lighter.
Answer: force, force
Explanation:
Newton’s third law states that there is an equal and opposite force
