Fc = (mv2)/r

100

What is the formula for centripetal acceleration?

Ac = v2/r

When a car is driving around a circular track, what is creating the centripetal force acted upon the vehicle and what direction is it applied?

The friction from the track is perpendicular to the velocity of the car, causing the circular motion

What is the centripetal acceleration of an object with a 12kg mass traveling in a circular path with a radius of 2m and velocity of 10m/s

50 m/s2

200

Which part of horizontal projectile motion does not need to be measured? And which part of horizontal motion is always zero?

Acceleration due to gravity is always 9.8 m/s2 so it does not need to be measured

Initial Velocity is always zero

What NBA team has the lowest social media following?

Minnesota Timberwolves

A 2 kg object is moving in a circle of radius 1.5 m with a speed of 4 m/s. What is the magnitude of the centripetal force acting on the object?

21.3 N

300

A ball is being swung in a circle on a string with a velocity of 5 m/s and a radius of 2 m. What is the centripetal acceleration of the ball?

12.5 m/s2

300

Why does the motion of a horizontal projectile become parabolic rather than diagonal?

As vertical velocity increases due to g, the vertical velocity will become increasingly greater than the horizontal velocity, causing the curvature.

What is the definition of a Newton?

The force required to accelerate 1kg of mass by 1m/s2

400

A car is traveling in a circular path with a radius of 40 m. If the centripetal acceleration of the car is 8 m/s², what is the car’s velocity?

17.89 m/s

400

Would a ball thrown horizontally and a ball dropped straight down reach the ground at the same time if they both had the same starting height? 

Explain why or why not.

Yes they would because horizontal and vertical velocity are independent of each other and objects, regardless of mass accelerate towards earth at a rate of 9.8m/s2

This means that while one may move horizontally, they both have the same vertical acceleration and velocity

What do Wilt Chamberlain, Paul Pierce and Andrew Wiggins all have in common?

They all went to Kansas

500

A 1,200 kg car is moving around a circular curve with a radius of 50 m. If the required centripetal force to keep the car on the curve is 18,000 N, what is the car's speed?

27.39 m/s

500

A 1,500 kg car is moving in a circular path with a speed of 20 m/s. If the car experiences a centripetal acceleration of 5 m/s², what is the radius of the circular path?

80 meters

500

Where is the only situation where centripetal force could equal to or less than centripetal acceleration?

Explain why/how.

The mass of the object must be less than or equal to 1kg which would create a force that is lesser than the acceleration because accel doesn't account for mass.
