Question

a body rotating with uniform angular acceleration covers 100 in the first 5s after the start. lts angular speed at the end of 5s is

Answer 1

General formula
θ = ω₀t + 0.5αt²

Substitute the known values
100 rad = 0 + [0.5 × α × (5 s)²]
α = 100 rad / (0.5 × 25 s²)
α = 8 rad/s²

Now, Angular speed after 5 seconds is
ω = ω₀ + αt
= 0 + (8 rad/s² × 5 s)
= 40 rad/s

Angular speed after 5 seconds is 40 rad/s

Answer 2
