Answer:
C. 3m/s
Explanation:
Since we ignore air resistant, horizontally speaking, theres no force acting on the ball. According to Newton's 1st law of motion, when there's no force, the object will stays in the same velocity.
In this case after, the ball velocity would still be 3m/s

Actually Welcome to the Concept of the Kinematics in real world.
So, as given here, we have to find the Mass of the bus from the given momentum, so we get as,
P = m * V
momentum = mass * velocity
here, P= 152625 kgm/s and v= 11.1 m/s
so substituting we get as,
m = 152625 ÷ 11.1 => 13,750 kg
hence,the mass of the bus is 13,750 kg.
After the ball leaves the bat, the only forces on it are air resistance and gravity.
Answer: 20 meters
Explanation:
This situation is related to vertical motion, especifically an object in free fall, and the parametric equation that describes this motion is:
![y=y_{o}+V_{o}t-\frac{g}{2}t^{2}](https://tex.z-dn.net/?f=y%3Dy_%7Bo%7D%2BV_%7Bo%7Dt-%5Cfrac%7Bg%7D%7B2%7Dt%5E%7B2%7D)
Where:
is the stone's final height
is the stone's initial height
is the initial speed of the stone
is the time the stone is falling
is the acceleration due gravity
Isolating
according to the given information:
![y_{o}=\frac{g}{2}t^{2}](https://tex.z-dn.net/?f=y_%7Bo%7D%3D%5Cfrac%7Bg%7D%7B2%7Dt%5E%7B2%7D)
![y_{o}=\frac{10 m/s^{2}}{2}(2 s)^{2}](https://tex.z-dn.net/?f=y_%7Bo%7D%3D%5Cfrac%7B10%20m%2Fs%5E%7B2%7D%7D%7B2%7D%282%20s%29%5E%7B2%7D)
Finally:
This is the distance the stone fell
Answer:
Mass is the inertia of object. Momentum is the inertia in motion.
Explanation:
Mass:- Mass is the measurement of inertia. Mass of an object depends upon number of atoms present in a object. its unit is kg. mass is the inertia of object.
Momentum:- It is the product of Mass And velocity.
Momentum is given by the formula P = m × v
Momentum is the inertia in motion. it increases with increase of mass , velocity or both increases.
Momentum unit is
