Answer:
<h2>f=a×m</h2>
m=1800kg
1800000g×10N/kg
18000000N force is required to life the car
The time interval in which the larger force act is 1.1 seconds.
<h3>What is impulse?</h3>
The impulse produced by an object is determined from the product of force and time of force of the object.
The impulse experienced by an object is the product of mass and velocity of the object or simply the impulse experienced by object is equal to change in the momentum of an object.
J = Ft
where;
- F is the applied force
- t is the time of force acting
The magnitude of the force that produce impulse of 3 Ns for 3.2 seconds is calculated as;
F = J/t
F = (3 Ns) / (3.2 s)
F = 0.94 N
The magnitude of the force that is three times larger is calculated as;
F₂ = 3 x 0.94 N
F₂ = 2.82 N
The time interval of the larger force is calculated as;
t₂ = J/F₂
t₂ = 3 / 2.82
t₂ = 1.1 seconds
Thus, the impulse experienced by an object is a function of force and time of force action.

Answer:
From the equation ΣF = ma, one can say that the mass is 1800 kg, and the acceleration of gravity is -9.8 meters. Multiply those together and it is -17640 newtons.

Explanation:
masa m de la barra de aluminio = 100 g
temperatura ambiente = 27 ° C
<em>Asumiremos que la barra de aluminio está en equilibrio térmico con el ambiente.
</em>
Esto significa que la temperatura inicial de la barra es de 27 ° C
temperatura final a la que la barra debe calentarse = 60 ° C
el aumento de temperatura ΔT será
ΔT = 60 ° C - 27 ° C = 33 ° C
capacidad calorífica específica c del aluminio = 0.215 cal/g°C
Calor C requerido = mcΔT
<em>C = 100 x 0.215 x 33 = 709.5 cal</em>
Answer:
The average speed is 
The average speed is different from the average velocity in this question
Explanation:
From the question we are told that
The equatorial radius of Jupiter is 
The period of oscillation of Jupiter is 
Generally the average speed is mathematically represented as
=> 
=>
Generally in average speed the direction is not considered while in average velocity the direction is considered for the case of this question the movement equitorial point has no direction in that it start from one point and after its periodic motion it still remains at that point
