Question

rojene
D. A body is projected from a point with differ
angles of projections 20. 35. 45°, 60°
the horizontal but with same initial speed. Their
respective horizontal ranges are R. R. Rand
R, Identify the correct order in which the
horizontal ranges are arranged in increasing
order
1) Rg, R₃, R₂R
3) R, R₂ R₃, R₂
2 R₂, R., R. Rz
4 R., R., R. Rz.​

Answer 1

Answer:R1, R2, R4, R3

Explanation:

R=u^2.sin2theta/g

Therefore

R1=u^2sin40°/g

R2=u^2sin70°/g

R3=u^2sin90°/g

R4=u^2sin120°/g

    =u^2cos30°/g

So,

Increasing order is

R1, R2, R4, R3
