average speed formula -ANSWER Vav= distance/time
A car travels 3,200m in 25mins. What's the average speed of the car?
A. 2.67 m/s
B. 2.13 m/s
C.88 m/s
D. 160 m/s -ANSWER B
Convert into seconds first
x/25mins=60s/1min; 25 x 60= 1500/1
3200/1500= 2.13 m/s
Velocity -ANSWER Speed in a given direction
scalar quantity
Vector quantity -ANSWER S: described by numeric value, expressed in units of
magnitude
V: describe time rate of change by object position, expressed in magnitude & direction
average velocity formula -ANSWER Final velocity + initial velocity / 2
Acceleration
Formula -ANSWER change in velocity over time
Formula: final velocity - initial velocity / time
Acceleration problem
A wagons set in motion. The wagon has an initial speed of 20 m/s and moves for 35
seconds. At the end of the 35 seconds, the wagon's speed is 50 m/s. What's the
magnitude of the wagons acceleration?
A. 0.3 m/s
B. 0.86 m/s
C. 1.37 m/s
D. 2.4 m/s -ANSWER B
projectile motion -ANSWER When an object is thrown, launched, or otherwise projected
near the surface of Earth
Horizontal motion of a projectile
Formula -ANSWER Not accelerated motion
Formula: dx= velocity x time
, Vertical motion of a projectile
The three formulas -ANSWER Accelerated motion
1. Vf^2= Vi^2 + 2ad
2. D= 1/2at^2 + Vi x T
3. Vf= Vi + at
A= 9.8 always
A ball is kicked off a cliff that is 23.7 m tall. The horizontal speed given to the ball is 14.0
m/s. Assuming there is no air resistance, how far out from the base of the cliff will the
ball land?
Figure out what you have first -ANSWER 30.8
A= 9.8 always
Didn't fall yet, Vi=0
First: use d=1/2at^2 + Vi x t
Then, d=1/2at^2 b/c vi is 0
Get t by itself, divide 1/2a, flip to top get 2d/a=t^2
3. Solve for time: t= square root d x 2 / a
Then, square root 23.7 x .8
T= 2
Next
Dx= Vt
Dx= 14.0 m/s x 2.2s
Dx= 30.8 m
Force -ANSWER A push or a pull
Newton's First Law
Formula -ANSWER an object at rest will stay at rest, an object in motion will stay in
motion unless acted on an unbalanced force
Formula: f= ka (constant proportionality times acceleration)
Newton's Second Law -ANSWER F=ma (mass times acceleration)
net force -ANSWER The sum of all forces acting on an object
+ and - signs for directions
Formula : nf= F left + (-) F right
A book rests on a tabletop. The book has a mass of 4 kg and is acted on by 2 forces.
The force pushing to the right is 56 N and the left is 145 N. Determine the magnitude of
the acceleration of the book, assuming there is no friction btn the book and table.
A. 12.5 m/s
B. 22.3 m/s
C. 37.4 m/s
D. 43.7 m/s -ANSWER First calculate force, Nf= f left + (-) f right
Nf= 145 N + (-) 56 N
Nf= 89 N left
