Ina shoots a large marble (marble a, mass: 0.08 kg) at a smaller marble (marble b, mass: 0.05 kg) that is sitting still. marble a was initially moving at a velocity of 0.5 m/s, but after the collision it has a velocity of −0.1 m/s. what is the resulting velocity of marble b after the collision? be sure to show your work for solving this problem along with the final answer.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
