Answer:

9.4m is the answer.

Step-by-step explanation:

a = 8m

b = 5m

c = ?

According to the Pythagoras theorem,

a² + b² = c²

8² + 5² = c²

64 + 25 = c²

89 = c²

c = 9.433

Rounding off,

c = 9.4m

The height H metres of a ball projected upwards t seconds after being projected is given by H=64t - 16t². Find it's initial velo

nordsb [41]

Answer:

initial velocity = 64 m/s

Step-by-step explanation:

Differentiate H = 64t - 16t² to find an equation for velocity:

Velocity = $\frac{dH}{dt}$ = 64 - 32t

Initial velocity (u) is when t = 0:

u = 64 - 32(0)

⇒ u = 64 - 0

⇒ u = 64 m/s
