Answer:
Part a)
Part b)
Ball thrown downwards =
Ball thrown upwards =
Part c)
Explanation:
Part a)
Since both the balls are projected with same speed in opposite directions
So here the time difference is the time for which the ball projected upward will move up and come back at the same point of projection
Afterwards the motion will be same as the first ball which is projected downwards
so here the time difference is given as
Part b)
Since the displacement in y direction for two balls is same as well as the the initial speed is also same so final speed is also same for both the balls
so it is given as
Part c)
Relative speed of two balls is given as
now the distance between two balls in 0.8 s is given as
Answer:
momentum , decreased , increase
Explanation:
I don't know if this is the answer your lurking for
This graph represents the relationship between v and t. It is shown that when t increases, v increases as well. So, these two values have direct proportional relationship.
Answer:
The distance of fly travel is 115.06 m.
Explanation:
Given that,
Distance = 115 mm
Speed = 1.10 m/s
Speed of fly = 2.20 m/s
We need to calculate the relative speed
Using formula of relative speed
Put the value into the formula
We need to calculate the time for the two steamrollers to meet each other
Using formula of time
Put the value into the formula
We need to calculate the distance of fly travel
Using formula of distance
Put the value into the formula
Hence, The distance of fly travel is 115.06 m.
