<h3>a. Let us assume a body has initial velocity 'u' and it is subjected to a uniform acceleration 'a' so that the final velocity 'v' after a time interval 't'. Now, By the definition of acceleration, we have:</h3>It is first equation of motion.
___________________________________
<h3>b. Let us assume a body moving with an initial velocity 'u'. Let it's final body 'v' after a time interval 't' and the distance travelled by the body becomes 's' then we already have,</h3>Putting the value of v from the equation (i) in equation (ii), we have,
It is third equation of motion.

<h3>c. Let us assume a body moving with an initial velocity 'u'. Let it's final velocity be 'v' after a time and the distance travelled by the body be 's'. We already have,</h3>Putting the value of t from (i) in the equation (ii)
It is forth equation of motion.

Good luck on your assignment..
Ball is thrown at an angle of 20 degree with velocity 18 m/s
so first we will find the two components of the velocity
similarly for other component
now the ball will cover horizontal distance of 30 m till it reach to other player
so here we can use the formula of time
so it will take 1.77 s to reach the other player
Answer:
Explanation:
So average velocity is calculated as
Hence in our given case total displacement would be 5 m as the car moves a distance 7m to 2m.
Time taken for this moment is given to be 3 seconds.
Hence substituting back we get the average velocity as
Hence this is the average velocity in this case.
