Question

in circular motion the centripetal acceleration is given by?
​

Answer 1

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

The centripetal acceleration is given by a c = ω 2 r . a_c=\omega^2 r. ac=ω2r. To calculate the biker's acceleration, find the change in the velocity vector Δ v ⃗ = v ⃗ ( θ + Δ θ ) − v ⃗ ( θ ) \Delta \vec{v} = \vec{v}(\theta+\Delta \theta) - \vec{v}(\theta) Δv =v (θ+Δθ)−v (θ), as the bike moves through the angle Δ θ .❤️

Answer 2

Answer:

Explanation:

linear velocity = w × r

if we differentiate linear velocty wrt t , get centripetal acc

a = alpha ×r
