s=vt...convert 45km/hr to m/s...45*1000/60*60=12.5m/s...s=12.5*20=250m

Formula; V=S/t.. DATA. V=45Km/hr, t=20s. S=?. convert 45km/hr to m/s, which is v=45x1000(m)/60x60(s)=45000/3600=12.5m/s. therefore puting the value in the above formula 12.5=s/20. cross multiply s=12.5x20. s=250m.(V=VELOCITY, S=DISTANCE & t= Time).

• Babypretty: Pls i want u to help me and solve this one. A planet has mass m1 and is at a distance r1 from the sun. A second planet has mass m2=10m1 and is at a distance of r2=2r1 from the sun. Determine the ratio of the gravitational forces experienced by the planet

S ={u+v}/2*t, u=0,v=45*1000/3600 =12.5m/s, distance ={0+12.5}/2*20 =125m

Using d formula for average distance covered,bcos d'velocity is constant,i.e its nt initial or final... S=(u+v/2)*t... Since d v is constant,den we hv S=(v/2)t... Converting 45km/hr to m/s, we have 12.5... (12.5/2)*20=125m.
