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?
2 answers:
Initial velocity = 20m/s
Accelerations = 3m/s^2
Time taken = 5s
Using second equation of motion
ut+(1/2)at^2
Where, s is the distance covered by the body
u is initial velocity
a is acceleration and t is time taken by that body
= (20)(5)+(1/2)(3)(5)^2
=100 + 37.5
= 137.5
So, the total distance covered by the body in next 5s would be 137.5m
The Correct answer to this question for Penn Foster Students is: 137.5 m

The car's average acceleration would be 1.25m/s^2 or 1.25meters/second/second. That looks to be the fourth one you've listed.
Answer:
Gravitational force.
Answer:60 ohms
Explanation:
R1=30 ohms
R2=15 ohms
R3=15 ohms
Let the total resistance be R
R=R1 + R2 + R3
R=30 + 15 +15
R=60
Total resistance is 60 ohms
v = x/t
v = average velocity, x = displacement, t = elapsed time
Given values:
x = 6km south, t = 60min
Plug in and solve for v:
v = 6/60
v = 0.1km/min south
I think D. It starts at (0.0) and goes to the correct points so it makes sense
