What is an object doing at the moment its instantaneous acceleration is zero?

Oliga [24]

Answer: Option A

Explanation:

Acceleration is defined as the rate of change of the vellocity.

Then, if the acceleration is equal zero, the object has a constant velocity or a velocity equal to zero (also constant, of course)

Then, te correct option would be option A; resting, because an object resting has instantaneuos acceleration of zero.

A 0.20-kg block rests on a frictionless level surface and is attached to a horizontally aligned spring with a spring constant of

solmaris [256]

Answer:

$0.57 ms^{-1}$

Explanation:

k = spring constant of the spring = 40 Nm⁻¹

A = amplitude of the simple harmonic motion = 4 cm = 0.04 m

m = mass of the block attached to spring = 0.20 kg

w = angular frequency of the simple harmonic motion

Angular frequency of the simple harmonic motion is given as $w = \sqrt{\frac{k}{m} } \\w = \sqrt{\frac{40}{0.20} }\\w = 14.14 rads^{-1}$

$v$ = Speed of the block as it pass the equilibrium point

Speed of the block as it pass the equilibrium point is given as

$v = A w\\v = (0.04) (14.14)\\v = 0.57 ms^{-1}$
