From Newton's second law, Force equals mass times acceleration, i.e F = m*a , So if the force F is constant implies m*a is constant , this inturn implies acceleration is inversely proportional to mass. So if the mass of the object is decreased then the acceleration of the object is increased. So the answer is A) the magnitude of the acceleration would increase.

The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...

Question 3 (1d motion, non-constant a) An object is recorded to move under the influence of the following acceleration. a(r)-(-카 s" The object was initially released from rest at the position x 20 m. Use this for the state of the object at time t 0 s. a. What is the velocity of the object at time t- 5 s? b. What is the position of the object at t 5 s? c. What is the displacement of the object...
A force of 1.15x103N is required to lift an object that is under the influence of an acceleration due to gravity of 7.76ft/sec2. What is the object's mass in kilograms?
A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...
Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 131 kg. Under the influence of a drive force of 245 N, it is moving at a constant velocity whose magnitude is 5.48 m/s. The drive force is then shut off. Find (a) the distance in which...
Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 171 kg. Under the influence of the drive force of 211 N, it is moving at a constant velocity whose magnitude is 5.88 m/s.

Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 136 kg. Under the influence of a drive force of 205 N, it is moving at a constant velocity whose magnitude is 5.50 m/s. The drive force is then shut off. Find the distance in which the...
If a single constant force acts on an object that moves on a straight line, the object's 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-vx, where k is a...
