the distance moved by a body at the end of t1=3s and t2=5s are 126m and 250m respectively. what is the initial velocity of the body.
s(t)=v0t+at22s(t) = v_0t +\frac{at^2}{2}s(t)=v0t+2at2
s(3)=3v0+4.5a=126(1)s(3)= 3v_0+4.5a =126(1)s(3)=3v0+4.5a=126(1)
s(5)=5v0+12.5a=250(2)s(5)= 5v_0+12.5a = 250(2)s(5)=5v0+12.5a=250(2)
From (1) and (2)\text{From (1) and (2)}From (1) and (2)
v0=27msv_0=27\frac{m}{s}v0=27sm
Answer:27ms\text{Answer:} 27\frac{m}{s}Answer:27sm
