Question

A body is accelerated from rest to a velocity of 50 m/s over a distance of 250 m . Calculate the acceleration.

Answer 1

Answer:

time = 250/50

= 5 s

acceletation = v/t

= 50/5

= 10 ms-¹

Answer 2

Explanation:

u = 0, v = 50 m/sec and s = 250 m

to find a

v² - u² = 2as

50² - 0² = 2 × a × 250

2500 = 500 × a

therefore a = 2500/500 => 5 m/sec²
