A car accelerates uniformly from 36 km/h to 72 km/h in 2 seconds. Calculate :a. The acceleration of the car b. The distance covered by the car in that time.

(a) The acceleration of the car is 5 m/s²

(b) The distance covered by the car in that time is 30 m

Step-by-step explanation:

Given;

initial velocity of the car, u = 36 km/h = 10 m/s

final velocity of the car, v = 72 km/h = 20 m/s

time for the motion, t = 2 seconds

(a) .The acceleration of the car;

v = u + at

(b) The distance covered by the car in that time

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

you are saying it as if a fact, not a question, but yes, you would be correct? ; )
