Question

A train starting from rest acquires a velocity of 54km/pr in 20 sec. Calculate the acceleration and distance travelled by it.

Answer 1

hello there!!!

u= 0 , v= 54km/h or 15 m/s , t= 20s
S = 15 × 20 = 300m

As we know that v²- u² = 2as
( 15 )² - 0²= 2× a× 300
a= 15 × 15/ 300× 2
a= 0.037 m/ s²

HOPE IT HELPS YOU...
