Asst 13 question 1
A ball rolls off the end of an incline with a vertical velocity of 20 cm/s downward, and a horizontal velocity of 80 cm/s. The ball falls freely to the floor 120 cm below.
• For the interval between the end of the ramp and the floor, what are the ball's initial velocity, displacement and acceleration in the vertical direction?
V0= 20 cm/s
Ds=120 cm
A= 980cm/s^2
#$&*
• What therefore are its final velocity, displacement, change in velocity and average velocity in the vertical direction?
@&
You know v0, `ds and a.
Which equation(s) of motion contain v0, `ds and a?
What quantities can you therefore determine from the given information?

• What are the ball's acceleration and initial velocity in the horizontal direction, and what is the change in clock time, during this interval?
#$&*
• What therefore are its displacement, final velocity, average velocity and change in velocity in the horizontal direction during this interval?
#$&*
• After the instant of impact with the floor, can we expect that the ball will be uniformly accelerated?
#$&*
• Why does this analysis stop at the instant of impact with the floor?

I dont know what to do. It may be the wording, but Im drawing a blank on how to do these problems.

I've inserted a few questions, which should be enough to get you started.
