To solve this problem it is necessary to apply the trigonometric ratios of the given velocity components.
If we make a graph of the velocity vectors in their respective velocities according to the given description we will have something similar to the attached graph.
The angle could be obtained from the components of the opposite leg and the adjacent leg so that
The opposite leg value (y) is 40cm / s and the adjacent leg (x) is 30cm / s
Therefore the final direction that does the first ball is 36.87°
Answer:
a) 5 m/s
b) 17.8542 m/s
c) 24.7212 m/s
0.229
Explanation:
t = Time taken
u = Initial velocity = 5 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
So, the stone would travel 1.27 m up
Velocity as the rock passes through the original point is 5 m/s
Time taken to reach the original point is 0.51+0.51 = 1.02 seconds
So, total height of the rock would fall is 30+1.27 = 31.27 m
Time taken by the stone to reach 15 m above the ground is 1.82+0.51 = 2.33 seconds
Speed of the ball at 15 m above the ground is 17.8542 m/s
Speed of the stone just before it hits the street is 24.7212 m/s
F = Force
m = Mass = 100 kg
g = Acceleration due to gravity = 9.81 m/s²
s = Displacement = 4 km = 4000 m
P = Power = 1 hp = 745.7 Watt
t = Time taken = 20 minutes = 1200 seconds
μ = Coefficient of sliding friction
F = μ×m×g
⇒F = μ×100×9.81
W = Work done = F×s
P = Work done / Time
⇒P = F×s / t
Coefficient of sliding friction is 0.229
