The acceleration of a particle is a(t) = 60t − 4t3 m/s2. Compute the average acceleration and the average speed over the time interval [3, 7], assuming that the particle's initial velocity is zero. (Round your answers to two decimal places.)

Explanation:

Acceleration function is given by

a(t) = 60 t - 4t³

To calculate the average acceleration [3,7] , use the following formula

Average acceleration = - 280 m/s²

velocity function is given by

Average velocity = - 38.2 m/s

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
