Answer:
t = 4 s
Explanation:
As we know that the particle A starts from Rest with constant acceleration
So the distance moved by the particle in given time "t"
Now we know that B moves with constant speed so in the same time B will move to another distance
now we know that B is already 349 cm down the track
so if A and B will meet after time "t"
then in that case
on solving above kinematics equation we have
Ball rolls down ramp, ball is released from spring, ball drops down chute.

Answer:
A, B, and E
Explanation:
C and D are wrong;
Line graphs do not show the dependent variable on the x-axis.
Line graphs do have both an x-axis and a y-axis.
Using
KE = ½mv² = ½×1500×19×19 = 270750 joules
