Free fall velocity
This task is about using a formula to create a table, graph and using these to make a prediction.
The formula for the velocity with which an object hits the ground after free falling is
v = 10t
|
|
v is the velocity in metres per second (m/s) t is the free falling time in seconds (s) |
a)
|
i)
|
Use the formula to complete the table. |
Time of free fall, t | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
Velocity, v | 0 |
ii) |
Plot the points in the table above, and join them with a line. |
Velocity of falling object
|
b) |
In a car-safety demonstration, cars are dropped vertically from a crane.
Emma counts 3.5 seconds between when a car is released and when it hits the ground.
What is the velocity of the car when it hits the ground? __________ m/s
