Answer to Problem 48QAP
Acceleration of the object when net force is doubled is
Explanation of Solution
Given:
Constant net force is applied to an object causes it to accelerate at
Formula used:
Newton's second law of motion,

- A force F applied to an object of mass m1, produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2. (a) What is the value of the ratio m1/m2,? (b) m1 and m2 are combined into one object, find its acceleration under the action of the force F.arrow_forwardDetermine whether each of the following statements is true or false. a. An objects weight is always equal to its mass. b. The force of tension always pushes. c. The magnitude of the sum of the forces on an object is never greater than its weight. Explain.arrow_forwardIf a single constant force acts on an object that moves on a straight line, the objects velocity is a linear function of time. The equation v = vi + at gives its velocity v as a function of time, where a is its constant acceleration. What if velocity is instead a linear function of position? Assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = vi kx, where k is a constant coefficient and x is the position of the object. Find the law describing the total force acting on this object.arrow_forward

Decrease the distance the force is appliedarrow_forward1. The acceleration of the object is _______ proportional to the net force and ________ proportional with its mass. a. directly ; inversely b. inversely ; directly c. inversely ; inversely d. directly ; directly 2. It is amount of pull of gravity on an object.a. Tension b. Frictional force c. Weight d. Normal forcearrow_forwardThe ratio of the force exerted on the foot by the ground to the persons body is 3.5 N/mg if the only forces acting on person are (i) the forced exerted by the ground and (ii) the persons weight, the magnitude of the person acceleration is 25 m/s^2.arrow_forward
- Two thieves want to steal a 1mx1mx1m Lazada Mystery Box worth of 1million pesos that is placed on a warehouse with a cemented floor. When they successfully break into the warehouse using a bobby pin they realize that they both cannot carry the 400 lb package, so they decided to push it out of the warehouse. If the untouched package and the cemented floor has a coefficient of friction of 0.400, what is the maximum amount of force they first need to exert in order to make the package move when they will: A) push the package with their hands 90 degree with the vertical wall of the box. B) push the package with their hands in 120 degree with the vertical wall of the package. C) When they decided to pull the box instead and their hands are in 120 degree with the top edge of the box. ASAParrow_forwardWhen a constant force is applied to an object the acceleration of the object varies inversely with its mass when a certain constant force acts upon an object with mass 20 kg the acceleration of the object is 2 m/s^2 when the same force acts upon another object it’s acceleration is 4 m/s^2 what is the mass of this objectarrow_forwardWhich of the following statements BEST describes Newton’s second law of motion? The object is either at rest or it moves with constant velocity when there is no net force acting on it. The force acting on an object is equal to its mass times its acceleration. An object with mass m subjected to a net force will have acceleration equal to the net force divided by its mass. When there is a net force acting on an object, the object moves with constant velocity equal to the net force divided by its mass.arrow_forward
