What is the density of the baseball?
2 answers:
The density of the baseball is
Explanation:
The density of an object is given by the equation
where
m is the mass of the object
V is its volume
For the baseball in this problem, we have:
m = 350 g is its mass
is the volume
Substituting into the equation, we find the density:
Therefore, the ball's density is outside the acceptable range.

Answer:
maximum possible velocity =
Explanation:
centripetal acceleration when the car is going in the circle must be less than the maximum friction for the car to not slip.
centripetal acceleration
where v is the velocity of car and r is the radius of circle
maximum friction = umg
where u is the coefficient of static friction.
therefore
therefore maximum possible velocity =
Answer:
h = 90.10 m
Explanation:
Given that,
A man is standing near the edge of a cliff 85 meters high, h₀ = 85 m
The initial speed of the stone, u = 10 m/s
The path followed by the projectile is given by :
....(1)
For maximum height,
Put dh/dt = 0
So,
Put the value of t in equation (1).
So, the maximum height of the stone is equal to 90.10 m.
