Question

From a standstill a car moves with a constant acceleration and covers 50m in 5s.
A) What is the velocity of the car after 15s?
B) How long will it take for the car to cover the next 30m?​

Answer 1

Answer:

Try doing it with the example. And never give up by any means.

Step-by-step explanation:

Calculating Final Velocity

An airplane lands with an initial velocity of 70.0 m/s and then decelerates at 1.50 m/s2 for 40.0 s. What is its final velocity?

Strategy

First, we identify the knowns: v0=70m/s,a=−1.50m/s2,t=40sv0=70m/s,a=−1.50m/s2,t=40s.

Second, we identify the unknown; in this case, it is final velocity vfvf.

Last, we determine which equation to use. To do this we figure out which kinematic equation gives the unknown in terms of the knowns.
