(b) Which part of the graph shows retardation? Also, calculate retardation.
(c) What is the acceleration of the body from B to C?
(d) Calculate the distance travelled till point A and from points C to D.
(e) What is the initial velocity of the object?

Answer 1

Answer:

1. the acceleration between point a and b is
2. $30 - 10 \div 250$
3. where 30 is final velocity and 10 is intial velocity .
4. The redartion of the graph is from c to d
