Question

a ball of mass 100g falls from a height of 100m on the ground. find the momentum of the ball transferred to the ground if it experiences acceleration of 10m/s^2 in forward direction

urgent please do it asap

Answer 1

Explanation:

velocity at just before touching ground (final velocity) is given by

$v ^{2} = u ^{2} + 2as$

$as \: u = 0$

$v ^{2} = 2as$

$v { }^{2} = 2 \times 10 \times 100 \\ v {}^{2} = 2000$

$v = 44.72 \\ momentum = mv$

$m = 0.1 \times 44.72 \\ 4.472kgm \div s$
