On the planet Gladdersnaq, Zarf the alien rolls a ball with an initial speed of 5.0 m/s across the horizontal ground. Zarf finds that the ball came to rest after rolling 9.2 m along the ground. Knowing that the coefficient of kinetic friction between the ground and the ball is 0.18, what is the value of g in m/s^2 on that planet?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
