+3 +3
21=21
Answer:
We have for velocity of package v= 20 - 9.8t and for distance from the ground y = h + 20t - 4.9t2.
We have y = 0 and t = 18.0 s we have h = 4.9·182 - 20·18 = 1227.6 m.
Velocity at landing v = 20 - 9.8·18 = - 156.4 m/s
Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1
