Mass and weight

Physics · Secondary 4 · Hard · Mass and weight

A 0.20 kg ball is dropped from rest on the Moon where the gravitational field strength is

1.6\,\text{N/kg}

. Assuming no air resistance, calculate the weight of the ball and hence its acceleration.

Weight = $0.32\,\text{N}$ , acceleration = $1.6\,\text{m/s}^2$
Weight = $0.32\,\text{N}$ , acceleration = $9.8\,\text{m/s}^2$
Weight = $1.6\,\text{N}$ , acceleration = $0.20\,\text{m/s}^2$
Weight = $0.20\,\text{N}$ , acceleration = $0.32\,\text{m/s}^2$
