Question

a car accelerates with 2 metre per second square from a speed of 80 kilometre per hour find the distance travelled and velocity reached in 25 seconds ?​

Answer 1

Answer:

a= 2m/s^2

u = 80km/h

= 80× 18/5 m/s

= 16 × 18 m/s

t = 25 sec

Explanation:

s = ut + 1/2at^2

= (16×18)25 + 1/2×2×25×25

= 7200 + 625

= 7825 m

= 7.825Km

Answer: distance covered in 25 sec is 7825m or 7.825Km
