The process which involves plants to cause weathering to a seed that falls into a crack in a rock therefore, breaking apart the rock is called Mechanical weathering.

<h3>Mechanical weathering</h3>

This is defined as the set of weathering processes that break apart rocks into particles (sediment) through physical processes. The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks then the water freezes and expands, therefore making the holes larger eventually making the rock split apart.

You're designing an airport.A plane that will use this airport must reach a speed of Vmin=100km/h(27.8m/s).It can accelerate at

Ilia_Sergeevich [38]

As here it is given that

x = 150 m

a= 2 m/s^2

now initial speed of the plane must be zero as it start from rest

now we will use kinematics

$v_f^2 - v_i^2 = 2 a x$
