Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
Explanation:
The principle of a lever is when two equal forces act in opposite directions and ultimately come to a state of equilibrium if distanced properly

There are 1,000m in a km, so 200km is 200,000m
200,000m/10m/s = 20,000s
Answer:

Explanation:
It is given that,
Mass of the baseball, m = 0.14 kg
It is dropped form a height of 1.8 m above the ground. Let u is the velocity when it hits the ground. Using the conservation of energy as :

h = 1.8 m

u = 5.93 m/s
Let v is the speed of the ball when it rebounds. Again using the conservation of energy to find it :

h' = 1.4 m

v = -5.23 m/s
The change in the momentum of the ball is given by :



So, the change in the ball's momentum occurs when the ball hits the ground is 1.56 kg-m/s. Hence, this is the required solution.
