Average Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
= 15 m/s - 24 m/s = -9 m/s
Acceleration = (-9 m/s) / (12 sec) = - 0.75 m/s² .
Answer:
Explanat Enthalpy of Vaporizationion:
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. ... Kinetic Energy: A force does work on the block. So the answer would be the first one.
Answer:
Thus it moves 1.7 mm sideways
Solution:
As per the question:
Mass of the television, m = 25 kg
Height of the rubber pads, h = 1.0 cm = 0.01 m
Radius, R = 0.60 cm = 0.006 m
Horizontal force, F = 200 N
Shear Modulus of Rubber, G = 
Now,
To calculate the distance moved:
G = 
G = 
where
= distance moved
Area of 4 rubber pads, A = 
Now,
