Question

I want some numericals or problem based on Graphical representation of motion for class 9​

Answer 1

Answer:

Explanation:

v2=u2+2as

Here u=x and a=-g,v=0

0=x2-2gs

s1=x2/2g

Similarly

for u=y and a=-g,v=0

0=y2-2gs

s2=y2/2g

So ratio of Height

s1/s2 = x2: y2

Now from Ist equation of motion

v=u+at

0=x-gt1

or t1=x/g

Similarly

t2=y/g

t1/t2 = x: y

Answer 2

Explanation:

1) a person complete 5 rounds revolution on a circular path of radius 50 metre find out the distance travelled by that person and magnitude of displacement

(Answer:- Distance=1570m, the magnitude of displacement=0)

2) the distance between Ahmedabad and Vadodara is 100km of scooterist travel at the average speed of 50 kilometre per hour if he travel for 60 kilometre at a uniform speed of 45 kilometre per hour what will be his speed for the remaining distance ?

(Answer:- 60 kilometre per hour)

3) a man walks 1.5 metre in the east direction then he walks 2.0 in the south direction and at least walk 4.5 metre in the east direction then using appropriate scale (1 cm =1 m) using scale....

(A) calculate the distance covered by the man

(B) find the resultant displacement (magnitude) of the man

(Answer:- (a) 8m (b) 6.3m )
