- On a strange planet the acceleration due to gravity is 20 ft/s^2 downwards towards the planet surface. If an object is launched from the ground with an initial velocity of 320 ft/s at an angle of 30 with the horizontal. Find the time the object is in the air, the time at which it reaches its maximum height and what that height is, and compute the tangential and normal accelerations at that point.An airplane makes a gradual 270° turn (heading goes from north to west to south to east) while flying at a constant speed of 212 m/s and maintaining the same altitude.

A player, starting at the y-axis, runs 8.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction). He then throws the football straight downfield 55.0 yards in a direction perpendicular to the y-axis (in the +x-direction).

The receiver that catches the football travels 64.0 additional yards at an angle of 45.0° counterclockwise from the +x-axis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run?
