A football punter kicks a football with a velocity of 22.0 m/s at 35.0 degrees from the horizontal. (a) Determine the initial horizontal and vertical components of the motion. (b) Calculate the time of flight of the football.  (c) Calculate the range (maximum x displacement) and the maximumheight of the football.

An airplane starts at rest and accelerates at 6.1 m/s2 at an angle of 38° south of west.After 11 s, how far in the westerly direction has the airplane traveled?

A student drives 10 km to the north and then 20 km 30 degrees South of the east. By using the component method, what are the magnitude and direction of his displacement from the starting point?

1) A student drove to the university from her home and noted that the odometer reading of her car increased by 15.8 km. The trip took 25.9 min. a) What was her average speed, in meters per second?  b) If the straight-line distance from her home to the university is 10.3 km in a direction 25° south of east, what was the magnitude of her average velocity in meters per second? c) If she drove back home using the same path she took out to the university and arrives 7.9 h after she first left home, what was her average speed for the entire trip, in meters per second?

A spider moves on a wall along the path shown in the figure. The spider's position and velocity is indicated at t; = 0 and t; = 6.00 seconds. The spider's initial velocity v; = 0.100 m/s is toward the North and final velocity vị = 0.100 m/s is toward the East. Determine the following: a) The x- and y-components of the displacement b) The x- and y-components of the average velocity c) The x- and y-components of the average acceleration. y (m) v = 0.100 m/s 0.350 = 0.100 m/s 0.150- x (m) 0.100 0.400

If a boat points its prow directly across a river, and its engine has one speed of 8.22 m/s. What is its speed, relative to the river bank, if the river has a velocity of 3.28 m/s? Number Units If the river is 63.4 m wide, how far down stream does it land when it reaches the opposite shore? Number Units
