Answer:
The force required will be "300 N".
Explanation:
The given values are:
Mass of object,
m = 300 kg
Acceleration,
a = 1 m/s
Now,
The force will be:
⇒
On substituting the values, we get
⇒
⇒
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,
