Question

multiple answer 1 point
a watermelon is dropped from the top of the c - building.
which two of the following can we assume about the watermelon?
its final velocity is equal to - 9.8 m/s.
its initial velocity is equal to 0 m/s.
it will reach terminal velocity and stop accelerating.
its acceleration is - 9.8 m/s².

Explanation:

Step1: Analyze initial velocity

When an object is dropped, its initial velocity \(v_0 = 0\ m/s\).

Step2: Analyze acceleration

Near the surface of the Earth, the acceleration of a freely - falling object (neglecting air resistance) is \(a=-g=- 9.8\ m/s^{2}\) (taking downwards as negative).

Answer:

Its initial velocity is equal to \(0\ m/s\); Its acceleration is \(-9.8\ m/s^{2}\)
