Be able to predict the result of pulses that meet...
Be able to describe what will happen when a pulse reaches each type of end (fixed or free).
Be able to sketch the types of standing wave for two fixed ends One fixed end one free end two free ends
A Hot wheels has a Eg of 10 J at the top of the ramp. At the bottom of the ramp the Ek is 5 J If the track was 5 m long, what is the force of friction?
Semina is at thet op of a skateboard ramp (40 kg, 6 m). She pushes with a force of 50 N for 3 m. What is her kinetic energy at the bottom of the ramp?
How fast is Maizy going when she hits the water?
example: Maizy is diving into Georgian Bay at the Grotto. At the top of the cliff her Eg is 5000 J. What is her kinetic energy when she hots the water?
example. Two boxes (20 kg and 30 kag) are pushed. They acclerate at 5 m/s^2[W]. What is the force of the large box on the small box? vice versa
example : Lucas (60 kg) and Elijah (80 kg) are having a disagreement on ice (zero friction). Elijah pushes Lucas with a force of 200 N[E]. What are their accelerations
Ethan and Sasha are pushing a box blah blah blah What is the velocity when they go 3m?
Example: Ethan and Mason are pushing a box (see above) The coefficient of kinetic friction is 0.17 Whast is the acceleration of the box?
Example. Luke pushes a 100 Kg box with a force of 200 N. The box accelerates at 1.5 m/s^2. What is the coefficient of friction?
Example: Ethan is pushing on a 30 kg box with a force of 100 N[E] What is the acceleraiton of the box? Mason is also pushing with a force of 50 N [N] What is the accleration with both of them pushing?
make one for the problem you are solving EVERY TIME
example: a ball is thrown vertically with a velocity of 15 m/s from the edge of a 10m cliff . - What is the vertical velocity? - what is the horoizontal velocity? - what is the total final velocity?
example: a ball is thrown vertically from the edge of a cliff with a velocty of 15 m/s from a height of 10 m. How far from the base does the object land?
example: a ball is dropped from a 10 m cliff. What is its velocity when it hits the ground
example: a ball is dropped from a height of 10 m, how long does it take to hit the ground
Example: Mason walks 5 km N[30]E Then he walks 3 km S How far east does he walk? How far North does he walk? What is his final displacement? (direction and magnitude)
Example: Semina walks 5 km N[60]E. how far north does she walk? how far east does she walk?
