5 kg basketball has more inertia than others.What is inertia?
According to the definition of inertia, matter has the ability to remain at rest or to move uniformly in a single direction unless applied with an external force.
For stationary or linearly moving material, mass acts as inertia of the object. Given objects are: 3 g gumball; 2 kg tennis ball; 2 g ping-pong ball; 5 kg basketball. Among these objects, the basketball has the most amount of mass. So, the basketball will have the most inertia.
Hence, the 5 kg basketball has the most inertia.

What is the speed of an object that is standing still?
On topographic maps, contour lines may change in width. True or False
The answer is true
A Cessna 150 aircraft has a lift-off speed of approximately 125 km/h. What minimum constant acceleration does this require if the aircraft is to be airborne after a take-off run of 205 m? Answer in units of m/s 2 .
The minimum acceleration is
The motion of the Cessna is a uniformly accelerated motion, so we can use the following suvat equation:
v is the final velocity of the Cessna
u is the initial velocity
a is the acceleration
s is the distance covered when accelerated from u to v
Assuming the Cessna starts from rest, we have:
u = 0
The final velocity (lift-off speed) is:
While the maximum distance that the aircraft can cover is:
s = 205 m
Therefore, the minimum acceleration that the Cessna should have is:
