Answer:
a)0.22 m/s².
Explanation:
Given that
Net force ,F= 6.8 N
mass ,m = 31 kg
From the second law of Newton's
F = m a ---------------1
Where
F=Net force ,m=mass
a=Acceleration
Now by putting the values in the equation 1
F = m a
6.8 = 31 x a
Therefore the acceleration of the scooter will be 0.22 m/s².
The answer will be "a".
a)0.22 m/s².
Answer:
Y=1370.23m
Explanation:
The motion have two moments the first one the time the initial velocity is accelerating then when the engines proceeds to move as a projectile
Now the motion the rocket moves as a projectile so:
Now the final velocity is the initial in the second one
The maximum altitude Vf=0
So total altitude is both altitude of the motion so:
