Answer:
The horizontal speed with which the slingshot hits the balloon is approximately 57.358 m/s
Explanation:
The given parameters of the slingshot motion are;
The initial velocity of the slingshot, v = 100 m/s
The angle (to the horizontal) at which the slingshot is fired makes, θ = 55°
The path of the slingshot which hits the stationary balloon at the top of its flight = Parabolic trajectory
The horizontal component of the velocity = vₓ = v·cos(θ) = Constant
vₓ = 100 × cos(55°) ≈ 57.358
The horizontal speed with which the slingshot hits the balloon = vₓ ≈ 57.358 m/s.
Answer:
300 N
Explanation:
The net force acting on the arrow is given by Newton's Second Law:
where
m = 0.06 kg is the mass of the arrow
a = 5,000 m/s^2 is the acceleration of the arrow
Substituting the numbers into the equation, we find
It is false it has straight sirface
Answer:
73 degree
Explanation:
Angle of incidence = 17 degree
According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
So, angle of reflection = 17 degree
Angle from the surface = 90 - 17 = 73 degree
