Sebuah kereta dengan kelajuan 50 m/s diberhentikan apabila breknya ditekan. Sesaran yang dilalui sebelum berhenti ialah 150 m. Berapakah nyahpecutan kereta itu?​

Deceleration a = -8.33 m/s²

Explanation:

Given:

Speed of car u = 50 m/s

Final speed of car v  = 0 m/s

Distance travel s = 150 m

Find:

Deceleration a

Computation:

v² = u² + 2as

0 = 50² + 2(a)(150)

- 2500 = 300a

Deceleration a = -8.33 m/s²

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
