Acceleration=non-uniform velocity/time
=displacement/time^2
Answer:
Snow
Explanation:
Precipitation is the formation of a solid after being a liquid. Snow, which is a solid, forms from water, a liquid.
Let the initial velocity be u = 23 m/s
Let the final velocity be v.
Vehicle stops finally, therefore v = 0 m/s
Here during the braking, vehicle decelerates with constant acceleration, thus the change in velocity is linear from initial velocity to final velocity.
for the Given condition:
Write the expression for the average speed
Substitute the values in the above expression.
Hence, the average speed during braking is 11.5 m/s
