Find the acceleration of a hamster when it increases its velocity from rest to 10 in 2.4
acceleration is change in velocity over change in time: ?v/?t where ?v is change in velocity and ?t is change in time in seconds.
the change in velocity is the difference between the final and initial velocities i.e. from rest to 10. If 10 is in m/s, then ?v = final velocity - initial velocity = 10m/s - 0m/s = 10m/s.
if 2.4 is in seconds, then simply divide this into 10m/s to get your acceleration;
(10m/s)/2.4s = 4.17m/s squared.

Express your answer to two significant figures and include the appropriate units.
To find the acceleration of the hamster, we can use the formula for acceleration:
acceleration = (final velocity - initial velocity) / time
Given:
Initial velocity (u) = 0 (rest)
Final velocity (v) = 10
Time (t) = 2.4 seconds
Substituting the given values into the formula:
acceleration = (10 - 0) / 2.4
acceleration = 10 / 2.4
acceleration ≈ 4.17
Therefore, the acceleration of the hamster when it increases its velocity from rest to 10 in 2.4 seconds is approximately 4.17 m/s².
To find the acceleration of the hamster, we can use the equation:
acceleration = (final velocity - initial velocity) / time
In this case, the hamster starts from rest, so its initial velocity is 0. The final velocity is given as 10. The time taken is 2.4 seconds.
Using the values, we can calculate the acceleration:
acceleration = (10 - 0) / 2.4
acceleration = 10 / 2.4
acceleration ≈ 4.17 m/s²
Therefore, the acceleration of the hamster is approximately 4.17 m/s².
