How long does it take the pebble to reach the ground?

A pebble dropped overboard would take just over an hour to reach the pitch-black seabed, where temperatures hover just above freezing and the pressure is over 1000 times higher than at the surface.

When you drop a stone from the top of a cliff and you have time value What formula would you use to find distance?

In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m .

How do you find the slope of 1 200?

For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200.

What is the final speed of the rock in the second half?

One should note that the initial speed of the rock in the second half is equal to the final speed of the first that is 31.3 m/s. The magnitude and the direction of the acceleration remains the same, therefore the final speed (say v)in this case can be calculated using equation (1).

What is the time taken by the rock to travel first?

Therefore the time taken by the rock to travel first is 50 m is 3.2 s. (b) When the rock has travelled first 50 meters, the motion for the next 50 meters can be analyzed using the same method as above. One should note that the initial speed of the rock in the second half is equal to the final speed of the first that is 31.3 m/s.

How do you find the free fall distance from 8 seconds?

In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s. Find the free fall distance using the equation s = (1/2)gt² = 0.5 * 9.80665 * 8² = 313.8 m.

How do you find the initial velocity of a falling object?

Decide whether the object has an initial velocity. We will assume v₀ = 0. Choose how long the object is falling. In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula v = v₀ + gt = 0 + 9.80665 * 8 = 78.45 m/s.
