Question

a drag racer starts from the rest and accelerates at 7.4m/s^2.how far will he travel in 2.0 seconds?

Answer 1

Answer:

14.8 m

Explanation:

S= ut + $\frac{1}{2}$a$t^{2}$

where u = initial velocity

S= (0 $\frac{m}{s}$)(2$s$) + $\frac{1}{2}$(7.4$\frac{m}{s^{2} }$)(2$s^{2}$)

S=  $\frac{1}{2}$(7.4$\frac{m}{s^{2} }$)(2$s^{2}$)

S=14.8 m
