a 10.0kg object moving at 5.00 m/s experiences a force of 20.0N. How far must it be pushed by this force for its speed to reach
15.0 m/s?
1 answer:
Answer: 50 m.
Explanation:
Assuming there is only 20N force acting on the object, use F = m * a where F is force, m is mass and a is acceleration.
You'll get a = 2.
Next, write what you know.
acceleration (a) = 2
initial velocity (u) = 5
final velocity (v) = 15
distance (s) = ?
Now, use v² = u² + 2as and find s.
