15 points bryan and reggie, two bicyclists are on a bicycle path. at first bryan is riding with a velocity of 4 m/s, and reggie is riding with a velocity of 3 m/s. two seconds later, both bicyclists have a velocity of 6 m/s. which statement best compares the accelerations of the two bicyclists? a. neither bicyclist accelerated. b. both have the same acceleration. c. bryan has a greater acceleration than the reggie. d. reggie has a greater acceleration than the bryan.

Riding your bike, you can accelerate at a rate of 2m/s^2. If you start from rest, how long will it take to reach a speed of 20m/s?

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
