Question

what is the answers of this 3 sub qustions?

Answer 1

1. uniform acceleration

2. the relation between displacement and time will be the area under the the which is straight line so the area that the straight line forms will be triangle

so area of the triangle will be 1/2*base*height = 1/2*time*velocity=displacement

so $x=\frac{1}{2}*time*velocity$

3. one
