Answer: Contact force
a. Applying break in a vehicle.
d. The speed of ball rolling on ground is reduced
Non contact force
b. A coconut falling from a coconut tree.
c. The planets revolving around the sun.
Explanation:
The contact force is the force which exerts when one object or entity comes in contact with other object or entity. For example, on application of break the vehicle stops, the force is applied on the breaks to stop the vehicle. The ball rolling on the ground the speed reduces so the application of force on the ground also reduces.
The non contact force is the force one object exerts on the other without coming in direct contact with the other object. The force exerted by one object on other due to gravity is a non contact force. The coconut falling on the ground and planets revolving around the sun are examples of non contact force due to gravity.
Well, it goes 60 miles in one hour......so set up a ratio.....
60 miles/5 miles = 1 hr/x.....you'll get 60x = 5....then 5/60 would be 0.083
The force applied on the football is 2.15 Newton.
Given the data in the question;
- Mass of football;
- Acceleration;
Force applied; 
To determine the force applied on the football, we use Newton's laws of motion:
Where m is the mass of the object and a is the acceleration.
We substitute our given values into the equation
Therefore, the force applied on the football is 2.15 Newton.

Answer:
Explanation:
As we know by the formula of elasticity that
now we have
Area = 15.2 mm x 19.1 mm
now we also know that force is given as
here we have
stress = Force / Area
now from above formula we have
Answer:
1. Energía = 4 J
2. Fuerza = 1,3 N
3. Aceleración = 2 m/s²
4. Masa = 7,1 kg
Explanation:
Magnitudes físicas y sus unidades;
1. Energía = 4 Joules
Energía se puede definir como la habilidad (capacidad) para realizar un trabajo.
2. Fuerza = 1,3 Newton
Fuerza = masa * aceleración
3. Aceleración = 2 m/s²
Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.
Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.
4. Masa = 7,1 Kilograms
La masa se puede definir como una medida de la cantidad de materia de la que se compone un objeto o un cuerpo. La unidad de medida estándar de la masa de un objeto o un cuerpo son los kilogramos.
