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

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

$F_{max} = 2\times 150.57$

$F_{max} = 301.14\ N$

If 2.0 j of work Is done raising a 180 g Apple how far was it lifted

andrew11 [14]

The apple is lifted by 1.1 m

<u>Explanation</u>:

Given that, mgh = 2 J and mass of apple = 180g
Step 1: convert grams to kg as work is given in SI units.

180 g = 0.18 kg

Step 2: substitute in the formula for work done.

0.18 * 10 * h = 2

Step 3: calculate the value of h from this formula.

h = 2/1.8

h = 1.11 m
