a water-balloon launcher with mass 4 kg fires a 0.5 kg balloon with a velocity of 3 m/s to the east. what is the recoil velocity of the launcher?
2 answers:
I think we will use the law of conservation of linear momentum; M1V1 = M2V2 M1 = 4 kg (mass of the water balloon launcher) V1=? M2= 0.5 kg ( mass of the balloon) V2 = 3 m/s Therefore; 4 V1 = 0.5 × 3 4V1= 1.5 V1= 1.5/4 = 0.375 m/s
Answer:
0.38 m/s west, for all a p e x users

Answer: C) 200 N
Explanation:
The force is defined as:
Where:
is the mass of the object
is the acceleration
Then:
Finally:
Hence, the correct option is C.
Time t=2.4 minutes=2.4×60=144 seconds distance s=1.2 miles=1.2×1609=1930.8 meters speed v=s/t=1930.8÷144=[tex] \frac{1930.8}{144} = \frac{160.9}{12} =[/13.408m/s ~nearly]
