What is the initial vertical velocity of a projectile with a launch velocity v at an angle (theta)
above the horizontal axis? - ANSvcos(theta)
What is the product of 0.89 and 172.1 using correct significant figures? - ANS150
In an air-free chamber, a pebble is thrown horizontally, and at the same instant a second pebble
is dropped from the same height. Compare the times of fall of the two pebbles - ANSThey hit at
the same time
0.0002468 can also be expressed as? - ANS2.468 x 10^-4
Which of the following is a vector quantity?
a) distance
b) time
c) acceleration
d) mass

How many significant figures are in the number 0.001802? - ANS4
For general projectile motion, the horizontal component of a projectile's velocity? - ANSRemains
a non-zero constant
A bullet is fired from ground level with a speed of 175 m/s at an angle 30.0 degrees above the
horizontal at a location where g = 10.0m/s^2. What is the vertical component of its velocity when
it is at the highest point of its trajectory? - ANS0 m/s
Suppose that an object is moving with a constant velocity. Make a statement concerning its
acceleration. - ANSThe acceleration must be equal to zero
A batter hits a baseball in a high arc toward center field. At the highest point in its trajectory: -
ANSNeither the ball's velocity nor its acceleration is zero
A rock is thrown upwards at an angle of 60 degrees with respect to the horizontal. As the rock is
rising in its trajectory, the vertical component of its velocity? - ANSDecreases
, A stone is thrown straight up. When it reaches its highest point, - ANSIts velocity is zero and its
acceleration is not zero
Mel is standing still and watching Alice and Flow move away from him in the same direction. If
alice is traveling at 2 m/s relative to Mel and Flo is moving at 1.5 m/s relative to Mel, what is
Alice's speed relative to Flo? - ANS+0.5 m/s
A car is traveling East and its velocity decreases. The acceleration of the car is in which of the
following directions? - ANSWestward
If a planet moves with constant speed in a perfectly circular orbit around a star, what is the
direction of the acceleration of the planet? - ANSInward toward the star
Pork Chop and Sue E. are riding on a merry-go-round. Sue E. is at a greater distance from the
axis of rotation than Pork Chop. Which of the following are true statements?
a) Pork Chop has a greater angular speed than Sue E.
b) Pork Chop has a smaller angular speed than Sue E.
c) Sue E. has a greater tangential speed than Pork Chop
d) Pork Chop and Sue E. have the same tangential speed - ANSC
A crate is sliding down an inclined ramp at a constant speed of 0.55 m/s. The vector sum of all
the forces acting on this crate must point?
a) down the ramp
b) up the ramp
c) perpendicular to the ramp
d) vertically downward
e) none of the above choices are correct - ANSE
Two equal-magnitude forces are applied to a door at the doorknob. The first force is applied
perpendicular to the door, and the second force is applied at 37 degrees to the plane of the
door. Which force exerts the greater torque about the door hinge?
a) the first force (applied perpendicular to the door)
b) the second force (applied at an angle)
c) Both forces exert equal non zero torques
d) both forces exert zero torque - ANSA
A satellite is in a circular orbit around Earth. Imagine what would happen if you could turn off
gravity. Without gravity, the satellite would now move? - ANSAlong a straight-line path in its
original direction
