1)Due to natural adaptation the bottom surfaces of camels feet are broad. Hence the camels weight is exerted on a large area and the pressure on the sand is reduced. Therefore camels feet do not penetrate into sand and it become easy for them to walk.
2)The main reason it is difficult to walk on sand is because the sand grains are unconsolidated (loose). So with each step you take, you just move the sand grains around (similar to the plastic ball pits that children play in). ... If the weather is hot, the sand can feel very hot
now use the
δd = vf*t - 1/2at^2
by setting the final time at the moment of the apex of the height, vf becomes 0.
so the equation will
δd = - 1/2at^2
the equation now resembles the change in height from the ground to the maximum height
δd = - 1/2at^2 = - 1/2 (-9.8 m/s^2) (3.125 s)^2 = 47.8 m
