Answer:
= 2.5km
Explanation:
Given: acceleration of car is 80km/h
Time: 15 seconds
To find: Acceleration in m/s and distance covered by car in 15 sec.
Solution:
ACCELERATION = 80km/h
= 80×1000m 200
----------------- = ------ = m/sec
60 ×60 sec 9
TIME = 15 sec
DISTANCE 1
= ut + ----- at²
2
here u=o, so,
S = 1/2 × at² = 1/2 × 200/9 × (15)²
S = 1/2 × 200/9 × 15 × 15 = 2500m
S = 2.5km. The position of the car the time it reaches 80 km/h is 2.5km.
