In a diving siblings showcase, 11-year-old Hannah takes off from a 24.61 foot platform with
an initial velocity of 9.7 ft/sec at the same time that her brother Tyler, who is 3.5 years older,
takes off from a 32.81 foot platform with an initial velocity of 4.51 ft/sec. Who enters the
water first? By how much? Round to the nearest hundredth.

Answer:

they hit the water at the same time

Step-by-step explanation:

11-year old hannah takes off from a 24.61 foot platform with an initial velocity of 9.7 ft/sec

Hannah's height at time "t": ht) = -16t^2 + 9.7t + 24.61

solve h(t) = 0 for the time her height is zero.

Ans: t = 1.58 seconds

at the same time her brother tyler, who is 3.5 years older, takes off from a 32.81 foot platform with an initial velocity of 4.51 ft/sec. Who enters the water first?

 

Brother's height at time "t": b(t) = -16t^2 + 4.51t + 32.81

Solve b(t) = 0 for the time his height is zero.

Ans: 1.58 seconds

They hit the water at the same time.
