A vehicle has uniform acceleration of 8 m/s2. What distance will it cover in 10 s after start ?A 200 m B 250 m C 100 m D 400 m
Question
A vehicle has uniform acceleration of 8 m/s². What distance will it cover in 10 s after start?
A. 200 m
B. 250 m
C. 100 m
D. 400 m
Solution
To solve this problem, we can use the equation of motion:
d = ut + 0.5at^2
where:
- d is the distance covered,
- u is the initial velocity,
- a is the acceleration, and
- t is the time.
Given that the vehicle starts from rest (u = 0), has an acceleration (a) of 8 m/s^2, and the time (t) is 10 seconds, we can substitute these values into the equation:
d = 010 + 0.5810^2 d = 0 + 0.58*100 d = 0 + 400 d = 400 m
So, the vehicle will cover 400 meters in 10 seconds after start. The correct answer is D. 400 m.
