Answer:
-235 m
Explanation:
The coin is a projectile in free fall. We can use kinematics to find the displacement as a function of the initial velocity, acceleration, and time.
Take up to be positive. Given:
u = -50 m/s
a = -9.8 m/s²
t = 3.50 s
Find: s
s = ut + ½ at²
s = (-50 m/s) (3.50 s) + ½ (-9.8 m/s²) (3.50 s)²
s = -235 m
