Answer:
The baseball will accelerate.
Explanation:
According to Newton's second law,
The force is the product of the mass and acceleration of the object.
In mathematically term
Where, m = mass
a = acceleration
If we hit a baseball with a bat it will accelerate by the applied force.
Hence, The baseball will accelerate.
B. 5 ft
C. 35 ft
D. 25 ft
Part (c) The rock is released from rest at point o Derive an expression for the speed v with which the rock crashes into a planet Part (d) Calculate the speed the rock crashes into the planet in m/s
The magnitude of the rock's acceleration half-way between two planets is 1.086 m/s².
The given parameters;
mass of planet, A = 3M
radius of the planet A, = R
mass of planet B, = 4M
radius of planet B, = 2R
distance between the two planets, r = 8R
The gravitational force half-way (4R) between the two planets is calculated from Newton's universal gravitational law as follows;
