Answer:
In m/s^2:
a=11.3778 m/s^2
In units of g:
a=1.161 g
Explanation:
Since the racing greyhounds are capable of rounding corners at very high speed so we are going use the following formula of acceleration for circular paths.
where:
v is the speed
r is the radius
Now,
In g units:
A rubber ball and a stone of the same size are examples which will have more inertia and is therefore denoted as option A.
<h3>What is Inertia?</h3>
This is referred to as the property exhibited by a body in which it has the tendency to remain at rest or in uniform motion.This property is dependent on the mass of the substance as we can deduce that the greater the mass, the greater the inertia and vice versa.
The size of a rubber ball and stone will have different masses in which that of the stone will be greater. This is as a result of the difference in the nature of the substances which are used to make both items mentioned above.
This is therefore the reason why a rubber ball and a stone of the same size as having more inertia(mass) where chosen as the most appropriate choice in this scenario.

Answer:
46.45 m/s
Explanation:
Total momentum before jump = Total momentum after jump
11.7 * ( 36.7 + 45.2 ) = ( 36.7 * (-31.1) ) + ( 45.2 * v )
v*45.2 - 1141.37 = 958.23
v = 2099.6/45.2 = 46.45
Answer:
A coefficient friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved.
