A motorbike is traveling to the left with a speed of 27.0 m s 27.0 s m 27, point, 0, start fraction, start text, m, end text,

Neporo4naja [7]

Answer:

Explanation:

Initial velocity , u = 27 m/s

displacement before stop, s = 41.5 m .

final velocity, v = 0

acceleration a = ?

v² = u² + 2 a s

0 = 27² + 2 x a x 41.5

a = - 27² / 2 x 41.5

= - 8.78 m /s

A car goes around a curve of radius 60 m at a constant speed of 15 m/s. Which of the following values is the centripetal acceler

IRISSAK [1]

Answer:

3.75 m/s^2

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by the equation:

$a=\frac{v^2}{r}$

where

v is the tangential speed of the object

r is the radius of the trajectory

In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is

$a=\frac{(15 m/s)^2}{60 m}=3.75 m/s^2$
