Question

a car travels a distance 100 M with a constant acceleration and average velocity of 20 m per second the final velocity acquired by the car is 25 m per second find the initial velocity and acceleration of car

Answer 1

HERE IS YOUR ANSWER

The distance travelled by car = 100 m
average velocity= 20 m/s
final velocity = 25 m/s

(initial velocity + final velocity) /2 = average velocity

Therefore
(u + 25)/2 = 20
therefore u = 15m/s

now we can use equation of motion ,

v-u =2as
25-15 = 2 a * 100
therefore a = 1/20 = 0.05 m/s².
