Multiple Choice

Aww snap, it's another vector (☞ﾟヮﾟ)☞

Find the vertical component of its velocity

• 52 m/s

• 30 m/s

• 35 m/s

• 9 m/s

Multiple Choice

A ball is thrown horizontally off a bridge at 15 m/s. Where will it be (x and y) in 1 second?

• x = 15 m

  y = -5 m

• x = 15 m

  y = -10 m

• x = 10 m

  y = -15 m

• x = 10 m

  y = -7.5 m

Multiple Choice

A cannon is fired horizontally from a 5.0 m tall tower. How much time will it take until the projectile hits the ground?

• 0.5 s

• 1.0 s

• 2.0 s

• 5.0 s

Multiple Choice

If the cannonball from the previous question is fired with a horizontal velocity of 140 m/s, how far will it travel horizontally?

• 141.4 m

• 282.8 m

• 176.3 m

• 83.8 m

Multiple Choice

The final requirement for a degree in geology is Field Camp, an 8 week field experience in which budding geologists must complete rigorous real-world mapping projects. To celebrate the end of field camp, one student threw his rock hammer off of a 78 m cliff with a horizontal velocity of 34 m/s. He was then reminded that he had one more day of field work, so he needed to go get his hammer. How far away from the cliff did he have to walk in order to find his hammer?

• 221.78 m

• 153.23 m

• 135.65 m

• 78.98 m

You are staying in a hotel with a balcony 45 m off the ground. There is a pool 18 m away from the edge of the balcony.

If you jumped horizontally from the balcony, how long would it take you to hit the ground?
