Answer:
no it will not glow hope help you stay happy
When a ball is dropped from building, it will experience two forces: gravitational force( acting in downward direction) and air resistance(acting in upward direction i.e opposite to the motion of ball). This air resistance can be neglected because coefficient of viscosity of air is very less. So only gravitational force is responsible for downward motion of the ball.
Answer:
33 hours or equivalently: 1980 minutes
Explanation:
Use the formula for movement under constant velocity, as the velocity equal the distance traveled divided by the time it took, and solve for the unknown time (t):
which can also be given in minutes as : 33 x 60 = 1980 minutes

The constant force required is 17.6 N
<u>Explanation:</u>
Given-
Mass, m = 0.55 kg
Initial speed, u = 0
Final speed, v = 8 m/s
Time, t = 0.25 s
Force, F = ?
We know,
Force = mass X acceleration
F = 0.55 X
F = 0.55 X
F = 17.6 N
Therefore, the constant force required is 17.6 N
