Answer:
2.88m/s
Step-by-step explanation:
By using the law of conservation of momentum
Initial momentum = final momentum
v = is their combined velocity afterwards
Solving equation (1) for v
V = 2.88 m/s
Therefore the velocity afterward is 2.88 m/s.
Answer:
8 wrong and 15 right if every question is the same points
Step-by-step explanation:
3.26/5 is 0.652
15/23 is 0.652 ish rounded
So I assume 8 wrong
Answer:
12
Step-by-step explanation:
29 = v + 17
29 - 17 = v
12 = v
Answer:
3(2y + 5) = -21
open the bracket
6y + 15 = -21
collect like terms
6y = -21-15
6y = -36
divide by the coefficient of y
y = 36÷6
y= 6
