A blue shark accelerates at a rate of 16m/s2 for a time of 0.8s. Durin – InterviewSolution

1.

A blue shark accelerates at a rate of 16m/s2 for a time of 0.8s. During this time it travels adistance of 11.52m. Calculate its initial speed. Please please please please help...

Answer»

EXPLANATION:

we the NEWTON's SECOND EQUATION

$s = ut + 1 \div 2at ^{2}$

a=16

t=0.8

s=11.52

$11.52 = u \times 0.8 + 1 \div 2 \times 16 \times (0.8) {}^{2}$

you will get

Ans 8m/s
