A roach moves down the hall at 1.2 m/s. When he sees the janitor coming down the hall, he begins to run. After 3.2 s, he is moving at 3.6 m/s. What is his acceleration

The acceleration is

Explanation:

Vo=Initial velocity

V= Final velocity

a= acceleration

t= time

V = Vo + a*t.

Vo = 1.2 m/s, V = 3.6 m/s, t = 3.2 s, a = ?.

3.6=1.2 + a x 3.2, so

3.6-1.2=3.2a

2.4=3.2a

a= 2.4/3.2

=0.75 m/s2

whats the drop down answers ?
