I need some help with this question, pls and thank you!! An object cannot have:
a) a velocity vector and an acceleration in the same direction.
b) a velocity vector and an acceleration in opposite directions.
c) a constant velocity vector and a variable acceleration.
d) constant acceleration and a variable speed vector

In which situation is the acceleration of a car negative? question 5 options: a)the velocity of a car was 75 km/hr over 4 hours. b)the velocity of a car reduced from 50 km/hr over one minute. c)the velocity of a car increased from 40 km.h to 75 km/h over 15 minutes. d)the velocity of a car was 45 km/hr at 2: 00pm and at 4: 00pm its velocity was 85 km/ht.
