the common attributes are positive and negatively charged
Explanation:
Given:
u = 20 m/s
a = 5 m/s^2
v = 30 m/s
t = ?
Use the first kinematic equation of motion:
v = u + at
t = (v - u)/a = 10/5 = 2 seconds
Answer:
Explanation:
El impulso aplicado a la pelota produce una variación en su momento lineal.
J = m (V -Vo)
Conviene elegir positivo el sentido de la velocidad final.
J = 0,100 kg [40 - (- 20)] m/s = 6 kg m/s

Initial speed is less than final speed
Answer:
Explanation:
Speed given = 125 m /min
125 /60 m /s
In 450 second it will travel
= 450 x 125 / 60
=937.5 m.
As the distance is covered in less than 450 seconds , The distance must be less than 937.5 m
In 400 seconds , it will travel
= 400 x 125 / 60
833.33 m
Since the distance is covered in more than 400 seconds , the distance must be more than ie 833.33 .
Hence the distance covered is more than .833 m but less than 937.5
In either case these distance are more than .8 km .
