Answer:
12.76 m.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 11.9 m/s
Angle of projection (θ) = 59°
Acceleration due to gravity (g) = 9.8 m/s²
Horizontal distance (i.e Range) (R) =?
The horizontal distance other wise known as range from the base of the building to which the rock will strike the ground can be obtained as follow:
R = u²Sine2θ / g
R = 11.9² × Sine (2×59) / 9.8
R = 141.61 × Sine 118 / 9.8
R = 12.76 m
Therefore, the horizontal distance from the base of the building to which the rock will strike the ground is 12.76 m
Answer:
average speed, accelerated speed
Explanation:
Pace was first moving at 38 km/h which was his average speed but the fastest speed he went was 60 km/h so he accelerated.
Answer:
Vr = 3.24m/s
The boat is going 3.24m/s relative to the bank of the river.
Explanation:
The relative speed of the boat to the bank Vr is the resultant of speed of boat relative to the water Vb and the speed of boat as a result of the water current or wind Vw
Vr = √(Vb^2 + Vw^2) .....1
Given;
Vb = 2.6m/s
Vw = distance downstream/time = 690m/355s
Vw = 1.94m/s
From equation 1 above; substituting the values
Vr = √(2.6^2 + 1.94^2)
Vr = 3.24m/s
The boat is going 3.24m/s relative to the bank of the river.
Answer to your question is B. I did a science lab over this...
Test was to see which would dissolve fastest... A tablet in warm water... and a tablet in cold water....
And this question isn't asking for solids or gasses.... because something dissolves with a liquid :P thanks...
Answer:
I cannot do the laws of physics cuz I hate science but I'm just dance
