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.
Signal detection theory is a theory that predicts how and when one detects the presence of weak stimuli admits background noise. The detection of stimuli involves decision and sensory processes. Factors that influence this detection include the intensity of the stimuli, physical factors such as fatigue and healthiness, and psychological factors such as motivation and expectations.
