Maira01:
with steps
:(
let me try .....wait a min or so
do you know components of vector
no
ok....is the angle of inclination given in the question
please answer this
:(
the answer will be gsin●
where g is accl due to gravity and ● is the angle at which the plane is inclined.

a) i)uniform acceletation since the graph is increasing. ii) unifor motion as the speed is not increasing. iii) retarding or deaccelerating as the graph is droping down. being a velocity time graph the graph repersents the displscement. and its slope gives the acceleration.
b) 40m/s is the highest velocity gained by the body
c) from A to B body is moving with uniform velocity.
d) a=v/t=30/3 = 10m/s²
e) the body drops from 40m/s to 0m/s in 3 seconds. a=40/3=13.3m/s²
d= area of triangle + area of rectangle = 1/2 *30 *3 + 30 *2 = 105m
