use the formula
v= u+ at
v is final velocity , u is initial velocity , a is acceleration and t is time
put the values
20 = 0+ a×5
a = 4 m/s²
If the object's velocity and acceleration have <em>opposite signs</em>, then the object is slowing down.

Answer:
F = 4.8 N
Explanation:
Given that,
Mass of the curtain, m = 1.2 kg
Acceleration of the pull, a = 4 m/s²
We need to find the force she exerts on the curtain.
We know that,
F = ma
Put al the values,
F = 1.2 kg × 4 m/s²
= 4.8 N
So, the force is 4.8 N.
A its Stratosphere, Sorry I didn't see your answer, its bilogy I think not physics.. :)
