Answer:
6.7 /s.
Step-by-step explanation:
Initial velocity = u m/s
From the question, final velocity, v = - 2u m/s
Note - (the minus sign indicates that the direction was reversed and doubled)
t = 0.45
From equation of motion,
v = u + at
Acceleration, a = (v - u)/t
= (-2u - u)/0.45
= - 3u/0.45
Acceleration, a/Original speed, u = 3/0.45
= 6.7 /s
Answer:
shortest side= x
longest side= x+8
other side= 3x
x+x+8+3x= 33
5x+8=33
5x= 25
x= 5
shortest side= x= 5
longest side= x+8= 5+8= 13
other side= 3x= 3(5)=15
Step-by-step explanation:
Answer:
1. a=2.3
2. b=2.6
3. c=2.3
4.d=2.6
5. e=40
6. f=1/6
7. g=85
Step-by-step explanation:
11-3 = 8
8y = 24
8y/8 = 24/8
y = 3
