Answer:
It’s b
Explanation:
Everyone else is wrong and I tried this and got it right
Answer:
M=125 kg
v=1.75 m/s
Explanation:
From the law of linear momentum
P =mv
Case 1 50*V =M* 0.7 equation 1
50*V =(M+50)* 0.5 equation 2
equating 1 and 2
M* 0.7=(m+50)* 0.5
0.2 M= 25
M=125 kg
Putting value of M in equation 1
50*V =125*0.7
V=1.75 m/s
3 is the answer teeeeeeeeeheeeeeeeee
Answer:
The answer is compound
Explanation:
heterogeneous mixture is wronggggg
D=m/V therefore the answer is 120/200 or 0.6
