Answer 1

1 constant motion

2 no acceleration

3 area of rectangle l*b

4 40 km

Answer 2

Explanation:

1. Since the Y-Coordinate is constant, the velocity is constant and hence it is Uniform Velocity Motion.

2. Since the velocity is constant, the acceleration of the body will be zero.

3. From the graph,

$-> Time=t_{2}-t_{1}=12-6=6sec$

$->Velocity=40m/s$

Distance = (speed)(time) = (6)(40) = 240m

4.Here, $t_{2}=10$

$->Time = t_{2}-t_{1}=10-6 = 4sec$

$->Velocity=40m/s$

Distance in 10 sec = (40)(4) = 160m.

Hope you've understood the answer.
