Question

draw the shape of the distance time graph for uniform and non uniform motion of object .a bus of starting from rest moves with uniform acceleration of 0.1 ms^-2 for 2 minutes .find
a,the speed acquired
b,the distance travelled​

Answer 1

Answer:

Uniform motion refers to a type of motion followed by an object where the speed or velocity of the object changes with respect to time whereas in a non-uniform motion, the velocity of the object “doesn’t change” with respect to the time.

Given data:

Acceleration a=0.1 \frac{m}{s^{-2}}a=0.1

s

−2

m

Time taken t=2 min ⁡= 120 s

The bus starts from rest so the initial velocity u will be zero, u = 0.

The distance ‘’s’’ travelled by bus can be found by the equation.

s=u t+\frac{1}{2} a t^{2}s=ut+

Substituting the values

s=0 \times 2+\frac{1}{2} \times 0.1 \times 120^{2}s=0×2+

s=720m.

The Travelled distance is 720m.

The speed of bus will be

speed=\frac{\text { distance }}{t i m e}speed=

time

distance

speed =\frac{720}{120}speed=
