Acceleration of the ball is
Explanation:
The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
For the ball in this problem, we have
m = 0.50 kg (mass)
F = 25 N (force)
thereofre, the acceleration of the ball is

Explanation:
It is given that,
Density of asteroid,
Mass of asteroid,
We need to find the diameter of the asteroid. The formula of density is given by:
V is the volume of spherical shaped asteroid,
r = 2441311.12 m
Diameter = 2 × radius
d = 4882622.24 m
or
Hence, this is the required solution.
Answer:
28 revolutions
Explanation:
Here we are going to use the accelerated angular motion formulas.
θ
because it starts from rest, wo=0
θ
θ
The number of revolutions is given by:
So the turbine completed 28 revolutions at that time.

Answer:
The speed of the electron is v = 1.01 x 10¹⁵ m/s
Explanation:
Given data,
The mass of the electron, m = 9.11 x 10⁻³¹ kg
The radius of the circle, r = 2.00 x 10⁻² m
The force acting on electron, F = 4.60 x 10⁻¹⁴ N
The speed of the electron, v = ?
The centripetal force of the electron is given by
F = mv² / r
∴ v² = Fr/m
v =√(Fr/m)
Substituting the given values in the above equation,
v =√( 4.60 x 10⁻¹⁴ x 2.00 x 10⁻² / 9.11 x 10⁻³¹ )
v = 1.01 x 10¹⁵ m/s
Hence, the speed of the electron is v = 1.01 x 10¹⁵ m/s
