Answer #1

Two objects collide on a frictionless surface. Object A with a
mass of 200g is moving in the positive x−direction with a speed of
1.0ms while object B, with a mass of 250g, is at rest. After the
collision object B is seen to have a speed of 0.40ms at an angle of
36.87◦ with respect to the positive x−axis. Find the magnitude and
direction of the object A after the collision. Find the kinetic
energy of the system before...

Object A (3 kg) and Object B (1 kg) are initially at rest. A
constant force of 2 N is applied to the two objects in the
following ways:
Scenario 1: The force accelerates both objects
over the same distance, d = 2 m.
Scenario 2: The force accelerates both objects
for the same length of time, Δt = 2 s.
Note that the force is applied in the same direction for both
objects.
After the acceleration, how do the...

A 60.0 N force is applied to an object initially at rest on a
frictionless surface, and the object moves 10.0 m in 4.00 s what is
the mass of the object? If the force stops being exerted on the
object after this first 4.00 s of motion, how far will it travel in
the next 4.00 s? [State the value, and briefly explain how you
determined it.

Two objects are dropped from the same height on earth. One has a
mass three times greater than the other one. If they are dropped at
the same time, assuming no air resistance, which of the following
statements is true?
The acceleration is the same for both objects, but the force on the
lighter object is greater.
The lighter object experiences one-third the force of the heavier
object, but the acceleration of the two objects are the same.
The lighter...

A block of ice with mass 6.00 kg is initially at rest on a
frictionless, horizontal surface. A worker then applies a
horizontal force F⃗ to it. As a result, the block moves along the
x-axis such that its position as a function of time is given by
x(t)=αt2+βt3, where α = 0.210 m/s2 and β = 2.07×10−2 m/s3
.Calculate the velocity of the object at time t = 3.50 s .Calculate
the magnitude of F⃗ at time t =...

A 14.7 kg object sits at rest on a 4.0 m long table. One half of
the table is smooth (frictionless) and the other half is rough. A
constant horizontal force of 12.3 N is applied to the object. (a)
What is the speed of the object after it has traveled 2.0 m? At 2.0
m, the constant force is removed and the block comes to rest after
traveling 1.75 m along the rough surface. (b) What is the magnitude...

A mass m is at rest on a horizontal frictionless
surface at t=0. Then a constant force
F0 acts on it for a time
t0. Suddenly the force doubles to
2F0 and remains constant until
t=2t0.
Determine the total distance traveled from t=0 to
t=2t0, in terms of the variables
m, F0, t0, and
appropriate constants.

Two charged objects 1 and 2 are held at a distance r
apart. Object 1 has mass m and charge +3q, and
object 2 has mass 2m and charge +q. The objects
are released from rest. Assume that the only force exerted on
either object is the electric force exerted by the other
object.
Part B
When the objects are at a distance 4r apart, what is
the speed of object 1?
Part C
When the objects are at a...

Block 1 has a mass of 0.35 kg and is on a frictionless surface.
It has an initial speed of 1.2 m/s and it elastically collides with
block 2 that was initially stationary. After the collision, the
first block has a speed of 0.2 m/s in the opposite direction.
a) What is the speed of block 2?
b) What is the mass of block 2?
c) If the collision time was 0.002 s, what was the average force
on block...

Two blocks are stacked as shown to the right and rest on a
frictionless surface. There is friction between the two blocks
(coefficient of friction μ). An external force is applied
to the top block at an angle θ to the horizontal. What is
the maximum force F that can be applied for the two blocks
to move together? Give your answer in terms of the variables from
the problem statement in addition to g for gravitational
acceleration.
