Science

28. A kangaroo hops 60 m to the east in 5 s
A kangaroo hops 60 m to the east in 5 s. What is the kangaroo’s average velocity?
Science

29. Science A kangaroo hops 60 m to the east in 5 s.
The kangaroo stops at a lake for a drink of water and then starts hopping again to the south. Each second, the kangaroo’s velocity increases 2.5 m/s. What is the kangaroo’s acceleration after 5 s?
Science

30. You know how to combine two forces that act in one or two directions
You know how to combine two forces that act in one or two directions. The same method can be used to combine several forces acting in several directions. Look at the diagrams, and calculate the net force in each diagram. Predict the direction each object will move.
Science

31. How is it possible to be accelerating and traveling at a constant speed?
Acceleration can occur simply by a change in direction. Thus, no change in speed is necessary for acceleration.
Science

32. Explain the difference between mass and weight.
Mass is the amount of matter in an object, and its value does not change with the object’s location. Weight measures the gravitational force on an object, so it can change as the amount of gravitational force changes.
