If you throw a 0.25-kg ball with a force of 20N what's the acceleration of the ball
Answers
20=0.25*a
a=20/0.25
a=80 m/s2
F/m=a
then a=Fm
a=20 x 0.25
a=5 m/s²

Answer is : 80 Newtons
Answer: The output force is 80 N.
Explanation :
It is given that,
Mechanical advantage of a machine is 4
Input force is 20 N
We know that the ratio of output force to the input force gives the mechanical advantage of a machine.
Where
F' is the output force
F is the input force
F' = 80 N
So, magnitude of output force is 80 N.

Momentum = Mass * Velocity
m = 2.20 g = 0.0022 kg
v = 0.850 m/s
Momentum = 0.0022 kg * 0.850 m/s
Momentum = 0.00187 kgm/s
Answer:
The momentum is actually 1.87 g m/s

Answer: (D). The unit and direction is missing.
Explanation:
Velocity: Velocity is the speed of the object with direction and it is the vector quantity. The unit of velocity is m/s.
Average velocity: Average velocity is defined as the total distance divided by the total time.
Here,
D = Total distance
T = Total time
According to the question:
The unit and the direction is missing in the cyclist's velocity.
Hence, The unit and direction is missing.

Answer:
Shown from explanation
Explanation:
You have heard that expression what ever goes up must come down that's usually used to mean when you throw an object up, it comes down on its accord. This is due to a force on the earth that occurs in nature known as gravity.
So when an object falls under this influence it's said to fall freely.
Note not all heavenly bodies have gravitational pull, from experience by scientists who went to the moon they found out whatever goes up keeps flying endlessly so in that case an external force is needed to keep objects in the moon on ground level.
Hence the parachute falls on earth freely without an external force but on the moon it must fall with an external force inputed on the parachute system.
This means in the earth we have free fall but in the moon no such thing exist. So a body falls freely when there is gravity.
