About 50 years ago, mounting evidence was suggesting
that the temperature of Earth's surface has been sharply
increasing for the past couple of centuries. Nowadays,
additional evidence no longer suggests it; it confirms it.
Today's mounting evidence suggests that human activity is
responsible for the increase, but that the increase eventually
spells curtains for much of human activity.
A= (v - u)/t
a= (40 - 0)/5
a= 40/5
a= 8m/s^2
Use conservation of momentum.
Initial momentum = 0
Final momentum = momentum of the girl + momentum of the boy = inifial momentum = 0.
Momentum of the girl = - momentum of the boy
mass of the girl * velocity of the girl = - mass of the boy * velocity of the boy
50 kg * velocity of the girl = - 80 kg * 3m/s
=> velocity of the girls = -80 kg * 3m/s / 50 kg = - 4.8 m/s
Answer: - 4.8 m/s
