Answer:
initial velocity = 64 m/s
Step-by-step explanation:
Differentiate H = 64t - 16t² to find an equation for velocity:
Velocity = 
= 64 - 32t
Initial velocity (u) is when t = 0:
u = 64 - 32(0)
⇒ u = 64 - 0
⇒ u = 64 m/s
Answer:
B. angle 5
Step-by-step explanation:
Answer:
THIS IS HARD
Step-by-step explanation:
The answer is b:
First change the operation to multiplication, and then change the last fraction to it's reciprocal (7/15 / 5/3)
Then, you can simplify 15 and 5 to 3 and 1 (divide each by 3)
Finally u multiply (7*1 / 3*3)
Sorry if its bad first time
