PDF-Slight acceleration in retail sales growth in April There was a slight improvement in

8 from 08 in March The April growth rate was however well down o n the 28 growth in the first four months of the year Furthermore on a m m seasonally adjusted basis there was no change in retail sales To some extent the outcome is slightly reassuring.

A constant non-zero net force applied to an object initially at rest will cause the object to move with . Objective: I will . identify the same value relating the measures of x and the measures of y in a proportional relationship as the constant of proportionality and recognize it as the unit rate in the context of a given situation. . The pitcher throws. The ball speeds toward the batter. Off the bat it goes. It’s going, going, gone! A home run!. Before landing, the ball went through several changes in motion. It sped up in the pitcher’s hand, and lost speed as it traveled toward the batter. The ball stopped when it hit the bat, changed direction, sped up again, and eventually slowed down. Most examples of motion involve similar changes. In fact, rarely does any object’s motion stay the same for very long.. Apparent Weight on a Roller Coaster. WDYS??? (p406). .. .. .. WDYT???.

When the light turns green, the car starts moving and the car’s velocity increased. The car began accelerating. Acceleration is the change in velocity divided by the time it took the change to occur.
