Answer
70 m/s, 140 m/s, 28 m/s²
Explanation:
Average velocity = total distance travel / time = 350 / 5 = 70 m/s
average velocity = (initial velocity + final velocity) / 2
70 × 2 = 140 m/s
change in velocity = final velocity - initial velocity = 140 m/s - 0 = 140 m/s
acceleration = (final velocity - initial velocity) / t = 140 m/s / 5 = 28 m/s²
Answer:
speed = distance/time
this is the equation substitute your values and get the answer....btw check you question again..
Acceleration occurs whenever the forces on an object are unbalanced.
It's the group of forces on the object that's either balanced or unbalanced.
There's no such thing as "an unbalanced force".
Answer:
when an object is moving
Explanation:
it turns into kinetic energy
