Question

the distance s cm. From the origin travelled in a straight line by a particle in the first t sec in given by s=2t^2+3t. Find the distance travelled in the 5th second​

Answer 1

Answer:

$equation \: given \: as \\ s = 2t {}^{2} + 3t \\ for \: time \: t = 5 \: sec \: put \: this \: value \: in \: above \: equation \\ thus \: we \: get \: s = 2 \times 5 {}^{2} + 3 \times 5 = 65 \: cm \\ ie \: \: s = 65 \: cm$
