A stone is tossed into the air from ground level with an initial velocity of 30 m/s. Its height at time t is h(t) : 30t – 4.9t2 m. Compute the stone's average velocity ū in m/s over the time intervals [2, 2.01], [2,2.001], [2,2.0001] and [1.9999, 2], [1.999, 2], [1.99, 2]. (Use decimal notation. Give your answers to three decimal places.) Ū12,2.01] = m/s Ü12,2.001] = m/s U12,2.0001] = m/s

An object is dropped from rest and takes 2.41 seconds to reach the ground below. From what distance above the ground was it dropped? State this as a positive number and assume it has proper SI Units.

A plane is flying to Minnesota with a velocity of 349.43 km/h, N. The plane encounters a crosswind with a velocity of 86.82 km/h, W. What is the magnitude of the resultant velocity of the plane? (Answer in km/h)
