Question

12 on a day when there is no wind an athlete runsa hundred metre mon 142cond
sketch graph showing her speed during the race is given in figure
10 calculate the acceleration of the athlete during the first 3 second of the race
alculate
(1) calculate the speed with which she process the finishing line
(11) suggest two differences that might be seen in the graph i there had been a strong
wind opposing the runner in the race.​

Answer 1

Answer:

Calculate displacement of an object that is not acceleration, given initial position and velocity.

Calculate final velocity of an accelerating object, given initial velocity, acceleration, and time.

Calculate displacement and final position of an accelerating object, given initial position, initial velocity, time, and acceleration.

Step-by-step explanation:

We might know that the greater the acceleration of, say, a car moving away from a stop sign, the greater the displacement in a given time. But we have not developed a specific equation that relates acceleration and displacement. In this section, we develop some convenient equations for kinematic relationships, starting from the definitions of displacement, velocity, and acceleration already covered.
