Answer:
S = 11.025 m
Explanation:
Given,
The time taken by the pebble to hit the water surface is, t = 1.5 s
Acceleration due to gravity, g = 9.8 m/s²
Using the II equations of motion
S = ut + 1/2 gt²
Here u is the initial velocity of the pebble. Since it is free-fall, the initial velocity
u = 0
Therefore, the equation becomes
S = 1/2 gt²
Substituting the given values in the above equation
S = 0.5 x 9.8 x 1.5²
= 11.025 m
Hence, the distance from the edge of the well to the water's surface is, S = 11.025 m
the answer is c: kilogram
explanation: The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice.
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.
