The acceleration of the ball is 1.27 X 10⁵ m/s²
The Newtons second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Given,
Mass = 145 kg
Force = 18,400 N
We need to calculate the acceleration
Using formula of acceleration(a)
a = F/m where F= force and m= mass
Put the values in the formula,
a = 18,400/(145 X 10⁻³) = 1.27 X 10⁵ m/s²
Therefor, the acceleration of the ball is 1.27 X 10⁵ m/s².

Answer:
a= 17.69 m/s^2
Explanation:
Step one:
given data
A car accelerates uniformly from rest to 23 m/s
u= 0m/s
v= 23m/s
distance= 30m
Step two:
We know that
acceleration= velocity/time
also,
velocity= distance/time
23= 30/t
t= 30/23
t= 1.30 seconds
hence
acceleration= 23/1.30
accelaration= 17.69 m/s^2
A number might be rounded when determining the number of people who will attend a basketball game. A number should not be rounded when determining the number of students who will participate in a chemistry lab. Only an estimate is needed for attendance at a basketball game because everyone will still get to see the game. In a chemistry lab the correct number of students should be known so that everybody has the proper equipment to use.
