Answer:
stone with lesser mass can not go far because of firm structure but football that has greatet mass can go farther because of the structure that makes it move further when a force was applied to it
The total momentum before and after the collision must be conserved.
The total momentum before the collision is:

where m1 and m2 are the masses of the two players, and

and

their initial velocities. Both are considered with positive sign, because the two players are running toward the same direction.
The final momentum is instead

because now the two players are moving together with a total mass of (m1+m2) and final speed vf.
By requiring that the momentum is conserved

we can calculate vf, the post-collision speed:


and the direction is the same as the direction of the players before the collision.
D. the motion of the source or observer
Answer:
The height of the water slide is 0.878 m
Explanation:
Given that,
Distance = 2.52 m
Suppose Children slide down a friction less water slide that ends at a height of 1.80 m above the pool.
We need to calculate the time
Using equation of motion

Put the value in the equation




We need to calculate the velocity
Using formula of velocity

Put the value into the formula


We need to calculate height
Using conservation of energy


Put the value into the formula


Hence, The height of the water slide is 0.878 m.
