Answer: it’s A
Explanation: hope this is right!!!!
Answer:
Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.

Answer:
76.4m/s
Explanation:
Given parameter:
Time taken = 7.8sec
Unknown:
Speed after it dropped = ?
Solution:
To solve this problem, we use one of the kinematics equation:
V = U + gt
V is the final speed
U is the initial speed = 0m/s
g is the acceleration due to gravity
t is the time taken
V = 0 + 9.8 x 7.8 = 76.4m/s
