Question

scooter initially at rest pick up a velocity of 20 ms-¹ is over a distance of 40 metre calculate acceleration and time in which it attention velocity of 20 ms-¹​

Answer 1

Answer:

${\small{\sf Acceleration\;is\;5\;m/s^2\;\& \;time\; is \; 4 \;sec}}$

Explanation:

Acceleration

v² - u² = 2as

(20)² - (0)² = 2(a)(40)

400 - 0 = 80a

400/80 = a

5 = a

Time

v = u + at

20 = 0 + (5)(t)

20 = 5t

20/5 = t

4 = t
