A motorcycle has a mass of 250kg. It goes around a 13.7 m radius turn at 96.5 km/hr. What is the centripetal force?
topjm [15]

Answer: c) 1.31 × 10⁴N

Explanation:

Centripetal force is a force that causes a body to move in a circular path. The body possesses a centripetal acceleration.

According to newtons first law

Force = mass (m) ×acceleration (a)

Acceleration of a body moving in a circular path = v²/r where;

v is the velocity and r is the radius

Force = MV²/r

Given m = 250kg v = 96.5km/hr r = 13.7m

We need to convert 96.5km/hr to m/s

= 96.5km ×1000/1hr × 3600

= 96,500/3,600

v = 26.8m/s

Force = 250 × 26.8²/13.7

Force = 13,106.5N

The centripetal force = 13,106.5N

= 1.31 × 10⁴N

Please help me, it's a simple equation
castortr0y [4]

Because the elevator moves at a constant speed, it's in equilibrium and the net force acting on it is zero. Then the tension in the cable exactly equals the magnitude of the elevator's weight, which is

(3000 kg) (9.80 m/s²) = 29,400 N
