Two water balloons of mass 0.35 kg collide and bounce off of each other
sladkih [1.3K]

Answer:

Option D

2 m/s East

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

Since the masses are the same then

m(u_1+u_2)=m(v_1+v_2)  

Therefore

u_1+u_2=v_1+v_2

where v_1 and v_2 are final velocities of objects while u_1 and u_2 are the initial velocities respectively

Taking East direction as positive then West as negative and by substitution

2.5+-2.25=v_1-1.75

Therefore

v_1=2 m/s hence East since it's positive

For the potential , determine the number of bound states?A)6 b)4 c) 3 d) 1
s2008m [1.1K]

Do you see that blank, open space after the word "potential ..." ?

There's supposed to be a number there that actually tells us the value of the potential.  Without that number ... and a lot more description of the whole scenario here ... there's no possible answer to the question.
