acceleration. =3m/s² time =10 s initial velocity(u)=0m/s v= at+u v=3×10+0 m/s v=30 m/s The distance covered is s metres (v² - u²) = 2as (30² - 0²)=2*3*s metres 900=6*s metres 900/6=s metres s= 150 metres. Ans: distance =150m

acceleration is uniform being 3m/s ^2. Hence a = 3 m/s^2 Time,t = 10 seconds Body starts from rest so u = 0 m/s We know that when u = 0 m/ s Distance , s = 1/2 a(t)^2 s = 1/2 × 3× 10 ×10 s= 150 m
