A map suggests that Atlanta is 730 miles in a direction 5.00c north of east from Dallas. The same map shows that Chicago is 560 miles in a direction 21.0 west of north from Atlanta. Figure P3.18 shows the location of these three cities. Modeling the Earth as flat, use this information to find the displacement from Dallas to Chicago. Figure P3.18
A rocket is launched at an angle of 53.0 above the horizontal with an initial speed of 100. m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
A football receiver running straight downfield at 5.50 m/s is 10.0 m in front of the quarterback when a pass is thrown downfield at 25.0 above the horizon (Fig. P3.58). If the receiver never changes speed and the ball is caught at the same height from which it was thrown, find (a) the footballs initial speed, (b) the amount of time the football spends in the air, and (c) the distance between the quarterback and the receiver when the catch is made.

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.23 m/s at an angle of 79.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.80 m above the table?
A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.39 m/s at an angle of 85.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 mabove the table?
A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.27 m/s at an angle of 69.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table? m/s
15. A ship bearing N 30-degrees W moves 3 hours at 17 miles per hour. It then turns 50 degrees starboard (to the right) to continue for 4 hours at 21 miles per hour. Finally the ship turns to a bearing of S 20-degrees E and travels for 1 hour at 12 miles per hour. Where is the ship's final location relative to its start?
2. A man walks westward on ship with a speed of 4 km/hr. The ship’s propeller drives it 15 km/hr south. What is the actual speed of the man relative to the earth? What is the direction of its velocity?
An object is moving in the x direction at 1.3 m/s when it is subjected to an acceleration given by a= 0.52j m/s2. What is its velocity vector after 4.4s of acceleration? Answer should be in components of vx and vy.
What are scalars vs vectors in physics? Position, velocity, and acceleration vectors?
