Question

A body moving with a velocity of 20 m/s begins to accelerate at 3 m/s2. How far does the body move in 5 seconds?

A. 137.5 m
B. 196 m
C. 260 m
D. 162.5 m

Answer 1

The Correct answer to this question for Penn Foster Students is: 137.5 m

Answer 2

The distance covered will be:


`d = v_0\cdot t + (1)/(2)a\cdot t^2 = 20(m)/(s)\cdot 5\ s + (5)/(2)(m)/(s^2)\cdot 5^2\ s^2 = \bf 162,5\ m`

The correct answer is D).
