Answer:
The state of being free from the effects of gravity.
Answer:
We know:
V1 = 0m/s
a = 9.8m/s
D = 16m
So we can solve for V2 with a kinematic equation.
V2^2 = 2a*D
V2^2 = 2(9.8)(16)
V2^2 = 313.6
V2 = 17.7m/s

Answer:
the ball experiences the greater momentum change
Explanation:
You have to take into account that momentum change is given by
where vf and vb are the speed of the object after and before the impact.
In the case of the ball you have
where the minus of vf is included due to the motion is in an opposite direction regarding with vb
And for the lump
Hence, the ball experiences the greater change
hope this helps!!
Answer:
sound of electronic means
Answer:
v = 12.79 m/s
Explanation:
Given that,
The mass of a car, m = 1200 kg
Momentum of the car, p = 15 350 kg-m/s
We need to find the velocity of the car. We know that, the formula for the momentum of an object is given by :
p = mv
Where
v is the velocity of the bject
So,
So, the velocity of the car is 12.79 m/s.
