The water balloon must accelerate m/s2.
Answer:
3.1 m/s²
Explanation:
Given:
Mass of the balloon (m) = 11.4 g = 0.0114 kg ( 1 kg = 1000 g)
Force acting on the balloon (F) = 0.035 N
Acceleration with which the balloon must be hit (a) = ?
Now, we know that, from Newton's second law, net force acting on an object is equal to the product of its mass and acceleration.
Therefore, framing in equation form, we have:
Rewriting in terms of acceleration 'a', we get:
Now, substitute the given values and solve for 'a'. This gives,
Therefore, the acceleration of the water balloon to reach the target must be equal to 3.1 m/s².
