An object starts moving from rest and it accelerates uniformly till 20 km per hour velocity after it applies break and speed reduces to 10 km per hour is a time taken by object in acceleration and the acceleration are 2 second and four second respectively find the acceleration and deacceleration?

An object starts moving from rest and it accelerates uniformly till 20...
Acceleration:
- Initial velocity (u) = 0 km/hr
- Final velocity (v) = 20 km/hr
- Time taken (t1) = 2 seconds
Using the formula: v = u + at
20 = 0 + a * 2
a = 10 km/hr^2

Decceleration:
- Initial velocity (u) = 20 km/hr
- Final velocity (v) = 10 km/hr
- Time taken (t2) = 4 seconds
Using the formula: v = u + at
10 = 20 + a * 4
a = -2.5 km/hr^2
The acceleration of the object is 10 km/hr^2 during acceleration phase and -2.5 km/hr^2 during the decceleration phase. The negative sign indicates that the object is decelerating.
