If the net force on an object is zero then
Group of answer choices
the object's speed can change.
the object must be at rest.
the object's speed is constant but its direction might be
changing.
the object has zero acceleration.
Besides the gravitational force, a 2.50-kg object is subjected
to one other constant force. The object starts from rest and in
1.20 s experiences a displacement of (5.40î − 3.30ĵ) m, where the
direction of ĵ is the upward vertical direction. Determine the
other force.
A force, in the direction of increasing x, acts on an object
moving along the x axis. If the magnitude of the force is F =
10·eN, where x is in meters, find the work done by the force as the
object moves from x = 0 to x = 2.0 m
plz answer asap! thank you
A constant force acts on a 600kg mass for 68s. The velocity of
the mass is 10m/s before the force is applied. Its final velocity
is 44m/s. What change in momentum does the force produce?
On which of the following does the moment of inertia of an object depend?
Check all that apply.
linear speed
linear acceleration
angular speed
angular acceleration
total mass
shape and density of the object
location of the axis of rotation
A constant force is applied to an object, causing the object to
accelerate at 6.0 m/s^2?
A. What will the acceleration be if the force is halved?
B.What will the acceleration be if the object's mass is
halved?
C. What will the acceleration be if the force and the object's
mass are both halved?
D. What will the acceleration be if the force is halved and the
object's mass is doubled?
A 50.0 g object is attached to a horizontal spring with a force
constant of 5.0 N/m and released from rest with an amplitude of
20.0cm. What is the velocity of the object when it is halfway to
the equilibrium position if the surface is frictionless?
