Two-Dimensional Motion and Vectors

A projectile is launched at 50m/s at 37∘. What is its speed at maximum height? (Take g\=10m/s2,cos⁡37∘\=0.8)

Projectile motion splits into horizontal uniform and vertical accelerated motion per NCERT Chapter 4. Range R=u²sin2θ/g and max height H=u²sin²θ/2g. Using given u, θ, g, calculation yields 40 m/s. Hence option D satisfies projectile formulas.

A projectile is launched at 16m/s at 37∘. What is its horizontal velocity component? (Take cos⁡37∘\=0.8)

Projectile motion splits into horizontal uniform and vertical accelerated motion per NCERT Chapter 4. Range R=u²sin2θ/g and max height H=u²sin²θ/2g. Using given u, θ, g, calculation yields 10 m/s. Hence option A satisfies projectile formulas.
