A car of mass m traveling at speed v, stops in time t when the maximum braking force isapplied.
Assuming that the braking force is independent of mass, what time would berequired to stop a car of
mass 2m traveling at speed v? - ANSWERS✔️💫-2t
Which would be the most comfortable temperature for your bath water? - ANSWERS✔️💫-310 K
In fundamental MKS units, intensity has a unit of - ANSWERS✔️💫-kg/s3
The period of a spring-mass system undergoing simple harmonic oscillation is T. If theamplitude of the
spring-mass system's motion is doubled, the period will be - ANSWERS✔️💫-T
A spring is compressed between two objects of unequal masses m and M. The objects areheld together
with a string. The objects are initially at rest when the string is cut. Whichstatement is true if the masses
are on a frictionless surface? - ANSWERS✔️💫-The magnitude of the linear momentum of the objects is
always the same
An object moves to the East across a frictionless surface with constant speed. A personthen applies a
constant force to the North on the object. What is the resulting path thatthe object takes? -
ANSWERS✔️💫-A parabolic path curving upward to the North
A small mass, m, hits a solid stick of mass M pivoted at one end. The mass hits the meterstick at its
bottom and sticks to it moving horizontally with speed v as it does. If one wantsto find the speed of the
, mass-meter stick system after collision, the best way to achievethis is to use - ANSWERS✔️💫-angular
momentum conservation
A point-like object is connected to the end of a string of length L. The string is pulledupward until it
makes a 90 degree angle with the vertical. The object of mass m isreleased from rest and swings through
a circular arc. What is the tension in the stringwhen the mass swings through the bottom of the arc? -
ANSWERS✔️💫-3mg
A box slides to the right across a horizontal floor. A person called Ted exerts a force T tothe right on the
box. A person called Mario exerts a force M to the left which is half aslarge as the force T. Given that
there is friction f and the box accelerates to the right, rankthe size of the forces exerted on the box -
ANSWERS✔️💫-f < M < T
An electron orbits a helium nucleus because of the electric force. The mass of the nucleusis 8000 times
that of the electron and the charge of the nucleus is twice the magnitude ofthat of the electron. What is
the ratio of the size of the force that the nucleus exerts onthe electron to the size of the force by the
electron on the nucleus? - ANSWERS✔️💫-1

the acceleration is zero, choose 0. The surface is frictionless and straightin the region of I. -
ANSWERS✔️💫-4
The acceleration of the block when in position II is best represented by which arrow? If itis zero, choose
0. The surface is frictionless. It is straight in the region of I. - ANSWERS✔️💫-1

the acceleration is zero, choose that. The surface is frictionless. It isstraight in the region of I. -
ANSWERS✔️💫-5
A pipe closed at one end and open at the other resonates at a fundamental frequency of240 Hz. The
next lowest/highest frequency at which it resonates is - ANSWERS✔️💫-720 Hz
Wind blows at 40 mph at 30o South of East with respect to the ground. A plane wishes tofly due South
with respect to the ground. If the speed of the plane with respect to the airis 145 mph, in what direction
should the plane be pointed? - ANSWERS✔️💫-76.2 degrees South of West
