A stone is tossed into the air from ground level with an initial velocity of 39 m/s. Its height at time t is h(t) = 39t − 4.9t^2 m/s. Compute the stone's average velocity over the time intervals

[1, 1.01], [1, 1.001], [1, 1.0001],

and

[0.99, 1], [0.999, 1], [0.9999, 1].

Estimate the instantaneous velocity v at t = 1.

is means division by fractions

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.
