Question

solve the questions plz plz plz​

Answer 1

number 1 the triangle is shown the distance travelled by the car so you take the formula area of the triangle and take the 1/2×4×20

=40 m/s.

the uniform motion is b to c and the declaration motion c to d

d= u-v/t

=14-20/4

=-6/4

=1.5 m/s^-2

Answer 2

Step-by-step explanation:

A))we will find area under graph for distance. take triangles A and B and find area by 1/2 ×l×b×h .

1)triangle A 1/2×20×4= 40

2)triangle B 1/2×20×4= 40

3) rectangle - l×b= 20×6= 120

Now add 40+40+120=200m

B)) From b to c is uniform motion as its moving with constant velocity.

From c to d is decelerated motion as it velocity is decreasing .
