Can someone ask me Toughest physics Question of class 9 or 10 or 11 for Anthe? I'm in class 9
Answers
Answer:
HEYA!!!
so your toughest question from class 9 physics are :-
1 )A particle moving in straight line experience constant acceleration for 20 second after starting from rest... If it travels a distance S1 in the first 10 second and S2 in the next 10 seconds then what is the relation between S1 and S2...?
2) a body travels a distance of 2metre in 2 second and 2.2 meter in next 4 second..What will be the velocity of the body at the end of 7the second from the start.... ?
3) A body traveling along straight line traveled 1/3rd of the total distance with velocity 4m/sec...The remaining part of distance was covered with velocity 2m/sec for half the time and 6m/sec for next half the time....Calculate avg..speed of whole motion....
4) If a body looses half of its velocity on penetrating 3cm in a wooden block, then how much will it penetrate more before coming rest.....?
5) A ball moves with a velocity of 5m/sec and collides with a box and returns with the velocity of 2m/sec...The box starts moving after collision and stops after covering 3m due to friction ....Find the work due to friction......
6) A ball of mass m is thrown vertically upward with a velocity u.....Find its potential energy at highest point.....
7) Derive the law of conservation of Energy......
8) a ball initially kept at highest point of a wedge...Find the speed of ball when it reaches the ground.....
HOPE IT HELPS........
u can solve all the questions.........

Explanation:
1.) s1 : s2 :: 1 : 3
Ratio of s1 and s2 is 1 : 3
