Calculating Time and Displacement for a Lab Cart
What is the initial speed of the lab cart?
The initial speed of the lab cart is 4.0 m/s.
What is the acceleration of the lab cart?
The acceleration of the lab cart is -3.0 m/s².
How can we calculate the time until the instantaneous velocity is zero?
Calculate the time until the instantaneous velocity is zero using the equation: final velocity = initial velocity + acceleration * time.
What is the time until the instantaneous velocity is zero?
The time until the instantaneous velocity is zero is 1.33 seconds.
How can we calculate the maximum displacement from the starting point?
Calculate the maximum displacement from the starting point using the equation: displacement = initial velocity * time + 0.5 * acceleration * time².
What is the maximum displacement from the starting point?
The maximum displacement from the starting point is 5.33 meters.
To calculate the time until the instantaneous velocity is zero, we can use the equation: final velocity = initial velocity + acceleration * time. Since the final velocity is zero and the initial velocity is 4.0 m/s, we can solve for time: 0 = 4.0 m/s - 3.0 m/s² * time. Solving for time, we get: time = 4.0 m/s / 3.0 m/s² = 1.33 s.
To calculate the maximum displacement from the starting point, we can use the equation: displacement = initial velocity * time + 0.5 * acceleration * time². Plugging in the values, we get: displacement = 4.0 m/s * 1.33 s + 0.5 * -3.0 m/s² * (1.33 s)². Evaluating this equation, we find: displacement = 5.33 m.
