Force, according to Newton's second law of motion, is calculated through the equation,
F = m x a
where F is force, m is mass, and a is acceleration.
We are already given with the mass of 103 kg, we therefore need to solve for the acceleration.
acceleration = (13.9 m/s - 1.4 m/s) / 1 s = 12.5 m/s²
Then, we substitute this value to the equation above.
F = (103 kg) x (12.5 m/s²)
F = 1287.5 N
Thus, the force involved in the collision is approximately 1287.5 N.
Answer:
168 Hz, 280 Hz and 392 Hz
Explanation:
The resonant frequencies for a closed pipe at one end is given by :
, n = 1,3,5...
The fundamental frequency, f₁ = v/4l = 56 Hz
For first overtone, put n = 3
For second overtone, put n = 5
For third overtone, put n = 7
So, the first three overtones are 168 Hz, 280 Hz and 392 Hz.
Answer:
the book is exerting a force of 15N on the table as we know that every action has an equal but opposite reaction so there must be a force acting on it in the opposite direction the other force normal force or we can say it perpendicular force that is defined as a contact force perpendicular to the contact surface that prevent two objects from passing over one another

Answer:
44 m
Explanation:
Given:
v₀ = 4.0 m/s
v = 18 m/s
t = 4.0 s
Find: Δx
Displacement is the average velocity times time:
Δx = ½ (v + v₀) t
Δx = ½ (18 m/s + 4.0 m/s) (4.0 s)
Δx = 44 m
Answer:
his speed is 5cm a second
