Chap 4 Motion in a plane​

Answer 1

Answer:

solved

Explanation:

6.

range R = u²sin2∝/g

height H = u²sin²∝/2g

H = R/2

sin²∝ = sin2∝ = 2sin∝cos∝

tan∝ =2

∝ = tan∧-1 (2)

choose answer (B)

----------------------------------------------

7.

Range = double max. height

R = 2H

H = v²/2g

R = v²/g

ans (A )
