-320<t because the temperature has to be greater then -320
Answer:
9-x
Step-by-step explanation:
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:
48
Step-by-step explanation:
120 divided by 2.5 = 40
Divide 7 by 32 and go from there
