Answer:
a) 7.848 m/s
b) 3.156 m
Explanation:
t = Time taken
u = Initial velocity = 1.75 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
His highest height above the board is 0.156 m
b) Total height he would fall is 3+0.156 = 3.156 m
He is in the air for 0.8+0.18 = 0.98 seconds
a) His velocity when he hits the water is 7.848 m/s
That would be an electron
