Answer:
20.65 m/s
Explanation:
You are gonna wanna use a calculator for this one
so we will write all the known variables:
h = 15.6 m
initial velocity (u) = 10.7 m/s
acceleration (a) = 10 m/s/s (gravity)
From the third equation of motion:
v² - u² = 2ah
v² - (10.7)² = 2(10)(15.5)
v² - (10.7)² = 312
v² = 312 + 114.49
v² = 426.49
v = 20.65 m/s
