The net force is (40 Newtons) (down the road).
But 40 Newtons is not going to move a piano very enthusiastically.
Answer:
The acceleration is -9.8 m/s²
Explanation:
Hi there!!
When you throw a ball upward, there is a downward acceleration that makes the ball return to your hand. This acceleration is produced by gravity.
The average acceleration is calculated as the variation of the speed over time. In this case, we know the time and the initial and final speed. Then:
acceleration = final speed - initial speed/ elapsed time
acceleration = -4.3 m/s - 4.3 m/s / 0.88 s
acceleration = -9.8 m/s²
The resultant force is 4 N to the right.
Explanation:
it could be possible if the car has all the right aro dynamics
