Answer:
The minimum time to get the car under max. speed limit of 79 km/h is 2.11 seconds.
Explanation:
isolating "t" from this equation:
Where:
a= (negative because is decelerating)
First we must convert velocity from km/h to m/s to be consistent with units.
So;
Answer: 14 speed of Earth around Sun I see 30 km/s. FALSE
15. Because car is in circle track, direction of velocity changes
And car is in accelerating motion. direction of acceleration points to
The centre of the circle. RIGHT
Explanation:
Explanation:
If acceleration points in the same direction as the velocity, the object will be speeding up. 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.
