A scooter weighing 150kg together with its rider moving at 36 km/hr is

1.	A scooter weighing 150kg together with its rider moving at 36 km/hr is to take a turn of radius 30 m. What force on the scooter towards the center is needed to make the turn possible? Who or what provides this? (Ans: 500N)
Answer» MASS of the scooter(m) = 150 kg. Radius(r) = 30 m. Velocity of the Scooter(v) = 36 km/hr. = 36 × 5/18 = 10 m/s. Using the FORMULA, Force = mv²/r ⇒ Force = 150 × 10²/30 ∴ F = 500 N. HENCE, the Centripetal Force of magnitude 500 N is acting on the scooter. Hope it helps.

Answer»

MASS of the scooter(m) = 150 kg.

Radius(r) = 30 m.

Velocity of the Scooter(v) = 36 km/hr.

= 36 × 5/18 = 10 m/s.

Using the FORMULA,

Force = mv²/r

⇒ Force = 150 × 10²/30

∴ F = 500 N.

HENCE, the Centripetal Force of magnitude 500 N is acting on the scooter.

Hope it helps.
