Aball is thrown upward at a 45° angle. inthe absence of air resistance, the ballfollows aa. tangential curve. b. sine curve. c. parabolic curve. d. linear curve.

As ball is projected up in air at an angle of 45 degree without any air resistance

Let the initial speed will be v

now we will have

In x direction

in y direction

now displacement in x direction

displacement in y direction

now from above two equations we have

so above equation is a quadratic equation and hence it will be a parabolic curve

so correct answer will be

C. parabolic curve.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
