An astronaut on the planet Zircon tosses a rock horizontally with a speed of 6.95 m/s . The rock falls through a vertical distance of 1.10 meters and lands a horizontal distance of 8.85 meters from the astronaut.

2. Relevant equations

3. The attempt at a solution

ΔX = 1/2(Vi + Vf)T

T = 2ΔX / (Vi + Vf)

T = (2)(8.85) / (9.95 + 0)

T = 1.778 s

ΔY = ViT + 1/2AT^2

ΔY - ViT = 1/2AT^2

A = 2(ΔY - ViT) / T^2

A = 2(1.10 - 0) / (1.778)^2

A = 1.58 m/s^2
