Answer:
176.58 m
Explanation:
t = Time taken = 6 seconds
u = Initial velocity = 0
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
Equation of motion

The object travels 176.58 m from the cliff in 6 seconds.
Speed=30 m/s - 1.5 m/s = 28.5 m/s forward
Calculated weight (by experimentally) of Earth is 5.972 × 10²⁴ N
Hope this helps!
