Answer:
Explanation:
Since the car is moving in a single direction, we can use the following kinematic equation to find its acceleration :
Where:
is the car's final velocity (we are told it comes to a stop)
is the car's initial velocity
is the car's acceleration
is the distance travelled by the car
Isolating :
Solving the equation with the given data:
Finally, the acceleration is:
Note the negative sign indicates the car was decreasing its velocity before coming to a stop.
Answer:
The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.
Answer:
True
Explanation:
A crowbar makes our work easier by multiply effort because it belongs to first class lever.
And first class lever makes work easier by multiplying the effort
O A large force can be exerted through a short distan
