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.)

On mars a rock falls an unknown vertical distance from a resting position and lands in a crater. if it takes the rock 2.5 seconds to fall, how high is the cliff the rock fell from? mars' surface gravity is 3.8 m/s2. a. 9.5 m b. 11.9 m c. 15.2 m d. 23.8 m

Is the vertical component of velocity ever zero?
