Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.
What is the first velocity of the car with two washers at the 0.25 meter mark?
m/s
What is the second velocity of the car with two washers at the 0.50 meter mark?
m/s
To calculate the first velocity of the car at the 0.25 meter mark, we need to use the formula v1 = 0.25 m / t1.
Assuming t1 is the average time it took the car to reach the 0.25 meter mark, let's say t1 is 0.5 seconds.
Substitute the values into the formula v1 = 0.25 m / 0.5 seconds = 0.50 m/s.
Therefore, the first velocity of the car with two washers at the 0.25 meter mark is 0.50 m/s.
To calculate the second velocity of the car at the 0.50 meter mark, we need to use the formula v2 = 0.25 m / (t2 - t1).
Assuming t2 is the average time it took the car to reach the 0.50 meter mark, let's say t2 is 1 second.
Substitute the values into the formula v2 = 0.25 m / (1 second - 0.5 seconds) = 0.50 m/s.
Therefore, the second velocity of the car with two washers at the 0.50 meter mark is 0.50 m/s.
