Question

2. If the initial speed of a car is 5 m/s and the acceleration is 2 m/s ^ 2 velocity of the car after 5 seconds in km/hr .​

Answer 1

Explanation:

Initial velocity = V(o)=5m/s and a=2m/s^²

we use the given equation V(t)=V(o) + at

V=15m/s =54km/hr

Answer 2

✪ Answer : ✪

We're given that, Initial velocity (u) of a car is 5 m/s and the acceleration (a) is 2 m/s². Time interval (t) is 5 second. We need to find the Final velocity (v) of the car in 'Km/hr'.

✪ CALCULATION ✪

We can calculate the final velocity (v) of the car by using first kinematical equation of motion.

→ v = u + at

Plug in the known values in the above given formula;

→ v = 5 + 2 × 5

→ v = 5 + 10

→ v = 15 m/s

→ v = (15 × 18)/5

→ v = 270/5

→ v = 54 km/hr

• Hence,the final velocity (v) of the car is 15 m/s or 54 km/hr.
