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:
(A) Impulse will be 1.116 kgm/sec
(B) Force will be equal to 1116 N
Explanation:
We have given mass of the basketball m = 0.120 kg
Initial speed of the ball
Final speed of the ball
(A) Impulse delivered by the ball is equal to the change in momentum
So impulse will be equal to
So impulse will be 1.116 kgm/sec
(B) Time is given for which force is exerted
We know that impulse is equal to
F = 1116 N
The eccentricity of its orbit is
<h3>What is mass?</h3>
- Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
- The kilogram is the SI unit of mass (kg). In science and technology, a body's weight in a given reference frame is the force that causes it to accelerate at a rate equal to the local acceleration of free fall in that frame.
- For instance, a kilogram mass weighs around 2.2 pounds at the surface of the planet. However, the same kilogram mass would weigh just about 0.8 pounds on Mars and about 5.5 pounds on Jupiter.
- An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
The length of the semi-major axis is calculated as follows:

To do this, multiply the vector's magnitude by the cosine of the angle of the vector to find the horizontal component and the vector's magnitude by the sine of the angle to discover the vertical component.
<h3>What horizontal and vertical components of this force?</h3>
The force's rightward and upward effects are described by the horizontal component, while the force's upward effect is described by the vertical component.
Therefore, We multiply the vector's magnitude by the cosine angle with respect to the horizontal in order to determine its horizontal component. We repeat the process, but this time we use the sine angle to get the vertical component.
