Easy -1.8 This is a straightforward one-step SUVAT problem requiring only substitution into v² = u² + 2as with u=0, a=9.8, s=40. It's simpler than typical A-level questions as it requires no problem-solving, just direct application of a single kinematic equation with all values given.
1.
In this question use \(g = 9.8 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
A ball, initially at rest, is dropped from a height of 40 m above the ground.
Calculate the speed of the ball when it reaches the ground.
