Question

Help please... the graph below shows how the velocity of a certain moving body varies time t.

Answer 1

(i)calculate the acceleration during the first 10s shown on the graph.
(ii)during the period t=30s to t=45s the body decelerates uniformly to rest.Complete the graph and obtain the velocity of the body when t=37.5s.
(iii)obtain the distance travelled by the body during the period t=30s to t=45s.

Answer 2

1) Acceleration is rate of change of velocity. So find change in velocity/10 seconds to get acceleration.

Answer 3

do u know how to calculate acceleration? i mean formula when u r given velocity and time

Answer 4

yes but i want to know the 2nd and third part

Answer 5

uniform deceleration means we have a straight line with negative slope. Complete the figure by this line.

Answer 6

can you show me drawing
