ICSE Class 8 Answered
An object changes it's velocity from 30 ms-1 to 40ms-1 in a time interval of 2s. What is it's acceleration?
Asked by dleena20 | 11 Jul, 2019, 08:03: PM
Expert Answer
v = u + a×t
where v is final velocity, u is initial velocity , a is acceleration and t is time duration in which velocity changes.
hence acceleration a = ( v- u ) /t = (40 - 30 )/2 = 5 m/s2
