Final answer:
The frequency of oscillations of the glider connected to springs on an air track is 7.49 Hz.
Step-by-step explanation:
To find the frequency of oscillations of the glider connected to springs on an air track, we can use the formula:
frequency = (1/2π) * √(k/M)
where k is the spring constant (given as 70 N/m) and M is the mass of the glider (given as 150 grams).
First, we need to convert the mass to kilograms by dividing it by 1000:
150 grams = 0.15 kg
Now we can substitute the values into the formula:
frequency = (1/2π) * √(70/0.15) = 7.49 Hz (rounded to two decimal places)
