Given :
- Acceleration (a) = 3.7 m/s²
weight is equal to :
Weight of the object is 0.37 Newtons ~
Correct choice is B
Answer:
The damping coefficient is 20.
Explanation:
Given that,
Spring constant = 50 N/m
Mass of block = 2 kg
We need to calculate the damping coefficient
Using formula of damping coefficient
In case of critical damping the damping rate is 1
Hence, The damping coefficient is 20.

Answer:
<em>The height of the cliff is 78.4 m</em>
Explanation:
<u>Horizontal Launch Motion</u>
When an object is thrown horizontally with a speed v from a height h, it describes a curved path exclusively ruled by gravity until it hits the ground.
The horizontal component of the velocity is always constant because no acceleration acts in that direction, thus:
The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:
Where g is the acceleration of gravity.
The maximum horizontal distance traveled by the object can be calculated as follows:
If the horizontal distance and the speed are known, we can solve the equation above for h:
The car leaves a cliff at a horizontal speed of v=15 m/s and hits the ground d=60 m from the shoreline. Thus the height of the cliff is:
Calculating:
h = 78.4 m
The height of the cliff is 78.4 m
