An initial velocity is:
v o = 25 m/s
The vertical component of the initial velocity:
v o y = v o * sin 60° =
= v o * √3 / 2 = 25 m/s * √3 / 2 = 21.65 m/s
Answer:
The approximate vertical component of the initial velocity is 21.65 m/s.
Answer:
Deceleration is the opposite of acceleration.
The mathematical formula for deceleration is:
Uniform deceleration of an object can be defined as decreasing the velocity of an object in equal amount in an equal interval of time.
The graph attached below shows a constant decrease in the velocity with a uniform time interval.
Answer:1
Explanation:
Let the heat given by flame be .
Let be the mass of water in case 1.
Let be the mass of water in case 2.
Let Δ be the temperature difference in case 1.
Let Δ be the temperature difference in case 2.
Let be the volume of water in case 1.
Let be the volume of water in case 2.
Let be the density of water.
Let be the specific heat of water.
Given,
Δ
Since the same heat is given to water in both the cases,
Δ
Δ
So,Δ=Δ
Since mass is product of volume an density,
Δ=Δ
Δ
So,Δ
That is meters per second, same as velocity.
The answer will be Amplitude.
