This is a retake for up to a 70%. If you would like to attempt for up to 80% you will need to come to tutorials for one single attempt at a FRQ.
Which direction will the centripetal force point?
What is the tangential velocity of a 700 kg car moving in a 35 m circle with an acceleration of 6.2 m/s2?
A penny was thrown downward at -2.4 m/s and falls under the influence of gravity for 5 s. What is the final velocity of the penny?
A projectile is launched horizontally at 2.6 m/s and falls 3.1 s later. How far away did it land?
A projectile is launched horizontally at 2.6 m/s and falls 3.1 s later. What is the height it was launched from?
Where is the vy= 0 m/s?
Where is the vertical a = 0 m/s2?
Which angle will produce the farthest range?
What is the vertical component of a ball thrown at a 27 degree angle at 16 m/s?
What is the horizontal component of a ball thrown at a 27 degree angle at 16 m/s?
A professional football player kicks a football with an initial velocity
vx= (15.0 m/s) vy= (19.0 m/s) . How long the football stays in the air is known as the hang time.
The hang time is
The total range is
The max height is
A cyclist with a mass of 80 kg is riding around a circular track with a radius of 100 m, and is traveling at 6.5 m/s. What is the cyclist's centripetal acceleration?
How does the centripetal force change if the tangential velocity is doubled?
The above soccer ball takes 3.4 seconds to land.
What is the height of the cliff?
What is the horizontal range?
What is the final vy?
What is the final vx?
What is the initial vy?
What is the time to fall?
What is the range?
Which direction will the tangential velocity point?
How does increasing the radius affect the centripetal acceleration?
