A car drives off of a cliff with a horizontal velocity of 46.0 m/s. If the car hits the ground 61.5 m from the base of the cliff, how high was the cliff? (Ignore air resistance)

- DONT HAVE A CLUE

How does the initial speed of a projectile fired at an angle compare to its final speed if air resistance is negligible and it lands at the same height from which it was fired?

- is the answer initial speed is same as final speed

How does the initial speed of a projectile fired at an angle compare to its final speed if air resistance is negligible and it lands at a lower height than it was fired?

- is the answer initial speed is slower than final speed

At what angle must a projectile be fired to produce the maximum hang time?

- is the answer 90 degrees?..........

a projectile is fired at 21° above the horizontal. If all other variables are held constant, what other angle will produce the same range?

- is the answer 111 degrees?

Why is the horizontal speed of a projectile constant when air resistance is ignored?

- is the answer there is no force slowing it down or speeding it up

Caribou walks 20.00 km south then turns west and walks 17.00 km. What is the magnitude and direction of Caribou’s total displacement?

is the answer: direction is south and displacement 3 km?............

If a 10 m/s vector is represented by a 5 cm arrow, then a 12 cm arrow represents a vector of what magnitude?

- is the answer 6 m/s

Keziah is standing still when she sees her daddy come home. She starts running toward him to give him a hug. If she accelerates to a speed of 2.72 m/s by the time she reaches him and it took her 3.2 seconds to get there, how far away was her daddy.
