a 2.00 kg friction-less block is attached to an ideal spring with force constant 315 N/m.Initially, the spring is neither stretc

Setler [38]

Answer

given,

mass of block, m = 2 Kg

spring constant, k = 315 N/m

speed of the block, v = 12 m/s

a) Amplitude of the motion

$A = v \sqrt{\dfrac{k}{m}}$

$A =\dfrac{12}{\sqrt{\dfrac{315}{2}}}$

A = 0.956 m

b) maximum acceleration of the block

$a_{max}= A \dfrac{k}{m}$

$a_{max}= 0.956\times \dfrac{315}{2}$

$a_{max}= 150.57\ m/s^2$

c) maximum Force

$F_{max} = m a_{max}$

$F_{max} = 2\times 150.57$

$F_{max} = 301.14\ N$

A car starts from rest and experiences a constant acceleration of 5 m/s2 until it reaches a speed of 650 meters

Zigmanuir [339]

Answer: Time.

Explanation:

Hey there!!!

The reason is,

According to the question we have,

Initial velocity = 0m/s { as it starts from rest}.

Final velocity = 650 m/s

acceleration = 5m/s^2.

Looking on this formula,

$a = \frac{v - u}{t}$

Where "v" represents final velocity, "u" represents initial velocity and "a" represents acceleration. We dont have is time "t".

So, it's obvious that tine is an unknown variable.
