Answer:
the gravitational force exerted on that object.
Explanation:
Apparent weight it a property. It tells how heavy an object is.app. wt. of an differ from the wt. of an object werever the force of gravity acting on the object is not balanced by an equal but opposite normal force...
Answer:
the speed of the center of mass of the two-particle system is 3.4 m/s.
Explanation:
Given that,
Mass of particle 1, m = 2 kg
Velocity of the particle 1, v = 4 m/s in +x direction
Mass of particle 2, m' = 3 kg
Velocity of the particle 2, v' = 5 m/s in +y direction.
The x -coordinate of velocity of the centre of mass is given by :
The y -coordinate of velocity of the centre of mass is given by :
So, the the speed of the center of mass of the two-particle system given by :
So, the speed of the center of mass of the two-particle system is 3.4 m/s.
Angular momentum about point O at this instant and the rate of increase in its speed using only kinematic equations is a= gsinθ.
Angular momentum =I.W
=mr²*V/r
Angular momentum=mvr
F=ma
mgsinθ=m.a
a=gsinθ
The kinematic equations are a collection of equations that explain the motion of an object with constant acceleration. Kinematics is a branch of physics that originated in classical mechanics and describes the motion of points, bodies, and systems of things without taking the forces that propel them. Kinematics is the study of the motion of mechanical objects, bodies, and systems without consideration of their related physical qualities and the forces acting on them. Kinematics equations need understanding of derivatives, rate of change, and integrals. The discipline, often known as the geometry of motion, employs algebra to mathematically represent these movements.

Answer:
<em>The rock reaches a maximum height of 442.225 m and was thrown at a speed of 93.1 m/s</em>
Explanation:
<u>Vertical Launch</u>
The rock is launched up with a certain speed vo, it reaches its highest point at a height h when the speed is zero, and then it stars a free-fall motion until it hits the ground at time t.
The maximum height is given by
The rock takes the same time to reach this point as to return to the ground, thus we can calculate the maximum height
The rock was thrown up at a speed
