<span> It will travel 1530 m* 6 seconds =9180m. thus the depth there will be 9180/2=4590m.</span>

0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary for

Paladinen [302]

Assuming the accleration applied was constant, we have

$v=v_0+at\implies v_0+20.0\,\dfrac{\mathrm m}{\mathrm s}=v_0+a(0.10\,\mathrm s)$

$\implies20.0\,\dfrac{\mathrm m}{\mathrm s}=a(0.10\,\mathrm s)$

$\implies a=200\,\dfrac{\mathrm m}{\mathrm s^2}$

Then the force applied to the ball is given by

$F=ma=(0.45\,\mathrm{kg})\left(200\,\dfrac{\mathrm m}{\mathrm s^2}\right)$

$\implies F=90\,\dfrac{\mathrm{kg}\,\mathrm m}{\mathrm s^2}=90.\,\mathrm N$

when the driver touches A Car steering wheel on a hot day heat is transferred to the driver's Hands by

Masteriza [31]

Heat is transferred to the driver's hands by conduction. The direct contact between the steering wheel and the driver's hands allows heat from molecules on the surface of the steering wheel to transfer to the molecules on the surface of the driver's hands. This is in contrast to convection (which requires a fluid in between the two surfaces that transfers heat).
