Question

(ii) displaceme
(iii) total displacement.
Ans. (1) AB : 7.5 m s-?, BC : 0 m s?, CD : - 15 m 52
(ii) AB : 60 m, BC : 120 m, CD : 30 m (iii) 210 m
11. A ball moves on a smooth floor in a straight line
with a uniform velocity 10 m s-l for 6 s. At t = 6 s.
the ball hits a wall and comes back along the same
line to the starting point with same speed. Draw the
velocity-time graph and use it to find the total
distance travelled by the ball and its displacement.
Ans. Distance = 120 m, displacement = 0.
2. Fig. 2.44 shows the velocity-time graph of a particle
moving in a straight line.​

Answer 1

Explanation:

(ii) displaceme

(iii) total displacement.

Ans. (1) AB : 7.5 m s-?, BC : 0 m s?, CD : - 15 m 52

(ii) AB : 60 m, BC : 120 m, CD : 30 m (iii) 210 m

11. A ball moves on a smooth floor in a straight line

with a uniform velocity 10 m s-l for 6 s. At t = 6 s.

the ball hits a wall and comes back along the same

line to the starting point with same speed. Draw the

velocity-time graph and use it to find the total

distance travelled by the ball and its displacement.

Ans. Distance = 120 m, displacement = 0.
