Answer:
Children = 2.25 ; Adult = 3.5
Explanation:
Given that :
Admission prices :
Let :
Senior fees = x
Children fees = y
2x + 9y = 36 - - - - - (1)
4x + 6y = 30 - - - - - (2)
Multiply (1) by 2 and (2) by 1
4x + 18y = 72 - - - (3)
4x + 6y = 30 - - - (4)
Subtract 4 from 3
12y = 42
y = 42 /12
y = 3.5
Put y = 3.5 in (2)
4x + 6(3.5) = 30
4x + 21 = 30
4x = 30 - 21
4x = 9
x = 9/4
x = 2.25
Children = 2.25 ; Adult = 3.5

Answer: 100N
Explanation: Given parameters:
Mass of the bowling ball = 20kg
Acceleration = 5m/s²
Unknown:
Amount of force applied = ?
Solution:
To solve this problem, we apply newton's second law of motion.
Force = mass x acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
