Projectile motion is a combination of which two types of motion?

The correct answer is:

Vertical Free Fall and Constant Horizontal Motion  

Explanation:

A projectile proposal is a form of motion confronted by an object or particle that is started near the Earth's surface and transfers along a rounded path under the action of gravity only. The vertical force acts perpendicular to the parallel motion and will not affect it since perpendicular segments of motion are confident of each other. Thus, the projectile travels with a constant horizontal velocity and a descending vertical acceleration.

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

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
