A bobsled accelerates from rest at a constant rate of 2 m/s2. How fast is it going after 3.5 seconds

7m/s

Explanation:

Using the equation of motion;

v = u+at

u = 0m/s

t = 3.5secs

a = 2m/s^2

Get the required velocity

v = 0 + 2(3.5)

v = 2(3.5)

v = 7.0m/s

Hence the body is moving with a speed of 7m/s

you have to draw the persons position over there
