In the absence of all air resistance what will fall faster a feather or a bowling ball?
They will fall at the same rate.
What is the acceleration in the y direction of all projectile problems
What is -9.81 m/s^2?
What is often the process for motion in 2D, for example what are we usually solving for?
Find the time and cross it to the other side to solve the problem.
This is acceleration in the x direction for all projectile problems
What is 0 m/s?
If you have a ball launched at some angle above the horizon with a speed of 75 m/s and the horizontal component is 25 m/s what is the angle launched at?
70 degrees
Draw the path of a cannon launched from a cannon ball.
What is a curved path? semi circle.
If a person takes a running leap off a high diving platform that they were running at and lands in the water 2.6s later how high was the platform
What is 33.16 m?
If a car drives off the cliff 100m high how would the horizontal component of the velocity compare 1s after driving off to 2 s after driving off
What is it would be the same... How about the vertical component (super bonus)
A projectile is fired horizontally from the top of a lab table that has a height of h, and it lands a distance x from the base of the table. Express the time of flight in terms of h,x, and/or g
What is squrt of 2h/g?
If a person is running at 2.8 m/s leaps off a high diving platform that they were running at and lands in the water 2.6 slater how far away from the platform will they hit the water.
What is 7.28 m?
A ball is projected horizontally from a cliff at a speed of 40 m/s if the ball travels a distance d, determine the distance in terms of d that a ball would travel if launched at 80 m/s from the same cliff
What is 2d?
A projectile is fired horizontally from the top of a lab table that has a height of h, and it lands a distance x from the base of the table. Express the initial velocity of the projectile in terms of h, x, g and/or t.
What is v = x/t?
