Marathon swimmer Jian is swimming in the Atlantic Ocean. She is moving north with a velocity of 2 m/s relative to the water. The ocean current is also moving north but at 1 m/s. What is Jian's absolute or true velocity?

A goalie completes a goal kick with the ball on the ground. The ball has a vertical velocity of 35 m/s and a horizontal velocity of 20 m/s when it leaves the goalie's foot. How long is the soccer ball in the air? Ignore air resistance. A.) 3.57 s B.) 2.04 s C.) 7.14 s

Which of the following quantities has units of a displacement? (There could be more than one correct choice.) 186,000 mi 40 km southwest 0-120 m/s O9.8 m/s2 O 32 ft/s vertically downward

Two students are discussing the motion of an object as it falls close to the earth.  Jerry makes the following statement: “The velocity of an object when it is falling close to the earth never changes because acceleration due to gravity is constant. “ Susan does not agree with Jerry.  Which reason below should Susan give to Jerry to correct his misconception?

If we know a truck is moving with a velocity 10.0 m/s at t = 0.0 s, and its velocity becomes 12.0 m/s at time t = 3.0 s. What is the position of the truck at t = 3.0 s ? O 5 m O 20 m O 30 m O 10 m O 33 m

Directions: Complete the table. Make a graph that best represents the behaviour of physical quantities. Behavior of Туре of Motion Displacement vs. Time Graph Velocity vs. Time Graph Physical Quantities - constant displacement - zero velocity Stationary Object or Object at Rest - zero acceleration - increasing or decreasing displacement - constant velocity - constant speed - no change in direction Constant Velocity or Uniform Velocity -zero acceleration - increasing or decreasing displacement - increasing or decreasing magnitude of velocity - constant speed but changing direction Constant Acceleration or Uniform Accelerated Motion - constant acceleration

A bug flies east at 2.5 m/s. A light breeze blows on the bug with a velocity of 2.5 m/s due east. What is the resultant velocity of the bug? O 5 m/s, east O 5 m/s, west O 2.5 m/s, east O 0 m/s

If a ball is thrown straight up into the air, what is its acceleration as it moves upward? How do I figure this out? it is asking for m/s

At t=0 an object has a velocity of 35 m/s and a steady acceleration of -10 m/s2.   Make a sketch of velocity vs. time for this motion from t=0 to t=5 s. Make a sketch of acceleration vs. time for this motion from t=0 to t=5 s. Does the object change directions between 0 and 6 s?
