You create a ramp using two text books and a 0.50m board. Using a timer you determine that a cart can roll down the ramp in 0.55s. Determine the velocity of the cart at the bottom of the ramp. How could you use this data to determine the acceleration?

The velocity of the cart at the bottom of the ramp is 1.81m/s, and the acceleration would be 3.30m/s^2.

Explanation:

Assuming the initial velocity to be zero, we can obtain the velocity at the bottom of the ramp using the kinematics equations:

Dividing the second equation by the first one, we obtain:

And, since , then:

It means that the velocity at the bottom of the ramp is 1.81m/s.

We could use this data, plus any of the two initial equations, to determine the acceleration:

So the acceleration is 3.30m/s^2.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
