Answer:
Lilly's speed is two times John's speed.
Explanation:
m = Mass
a = Acceleration
t = Time taken
u = Initial velocity
v = Final velocity
The force they apply on each other will be equal
Hence, Lilly's speed is two times John's speed.
Velocity of the object parameters would affect the fall if air drag is also considered.
<h3>What is velocity in physics with example?</h3>
Velocity can be defined as the rate at which that moves in a specific direction. as the velocity of a car driving north on a road or the pace at which a rocket takes off. Because the velocity vector is scalar, its integrand magnitude will always equal the motion's speed.
<h3>Can velocity be negative?</h3>
A moving object has a negative velocity when it is moving in the wrong direction. If an object is slowing down, its generate and evaluate is pointing away from the direction in which it is moving (in this case, a positive acceleration).
<h3>What is the principle of velocity?</h3>
An object must move at a constant speed and direction in order to have a constant velocity. The object can only travel in a straight line if the direction is constant. So, motion in a single direction at a constant speed is defined as having a constant velocity.

You are correct earth science is studied to predict planetery changes
Answer:
acceleration = cange in velocity ÷ change in time.
acceleration = (-15 - -10) ÷ 2
acceleration = -5 ÷ 2
ACCELERATION IS -2.5m/s2
