The Stunt Driver: Jason's Cliff Jump Calculation
Jason's Stunt: Calculating Time and Distance
Jason is a stunt driver who jumps off a cliff with a speed of 25 m/s. The cliff's height is 30 meters. We need to determine how long he remains in the air and how far from the bottom of the cliff he lands safely.
Final Answer:
Jason remains in the air for approximately 2.47 seconds and lands 61.75 meters away from the bottom of the cliff.
Explanation:
In this scenario, we can use equations of motion under gravity to solve the problem. First, we calculate the time Jason is in the air. The formula to calculate time is derived from the equation of motion: distance = initial velocity x time + 0.5 x acceleration x (time^2).
Given that the acceleration due to gravity is -9.8 m/s^2 and the initial velocity is 25 m/s, we use the formula: t = sqrt((2*distance) / acceleration). Substituting the values, we get t = sqrt((2*-30)/-9.8) ≈ 2.47 seconds.
Secondly, to calculate how far Jason lands from the bottom of the cliff, we consider his horizontal movement. Since there is no horizontal acceleration, we use the formula distance = speed x time.
Therefore, d = 25m/s x 2.47s = 61.75 meters. This means that Jason lands 61.75 meters away from the bottom of the cliff.
