A projectile is launched at an angle of 30°to the horizontal from 6.5 ft above the ground at an initial speed of 100 ​ft/sec. Assume the​ x-axis is​ horizontal, the positive​ y-axis is vertical​ (opposite g), the ground is​ horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors for t≥0. b. Determine the time of flight and range of the object. c. Determine the maximum height of the object.

A ball has an initial velocity of 160 m/s at an angle of 30 degrees horizontally. This means that the initial vertical velocity of 80m/s and its initial horizontal velocity is 139m/s. Find its position and velocity after 5 seconds. a. Horizontal Displacement b. Find the Vertical Displacement c. Horizontal and Vertical Component of Velocity

student throws a heavy red ball horizontally from a balcony of a tall building with aninitial speed v0. At the same time, a second student throws a lighter blue ball horizontally fromthe same balcony with an initial speed v0 /2. Ignoring air resistance, which of the followingstatements must be true?a. The red ball hits the ground with the greater speed.b. Both balls hit the ground with the same vertical velocity component.c. Both balls hit the ground with the same angle of impactd. The balls reach the ground at the same instant.     More than one of the statements can be true.

At the beginning of a 3.0-h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 239 km/h in the northwest direction (45° west of north). a. Which of the following are the initial and final velocity vectors? SEE ATTACHMENTS b. Find the magnitude of the change in velocity. anser in km/h c. Find the change in direction of your velocity. Enter the angle in degrees where negative indicates north of west and positive indicates south of west. answer in degrees d. What is the magnitude of your average acceleration during the trip? answer in km/h^2
