Question 1
A body ……… friction
Answer
Again acceleration due to friction
⇒ -ug = -1
or ⇒ u = 1 / 10
⇒ = 0.1
Question 2
A block of mass …………… in term of g
Answer
Question 3
Two block …………… Two block
Answer
Question 4
A car is moving ………………stopped
Answer
accerelation on car = – ug
⇒ 0 =20 x 20 + 2 (-u) x s
or ⇒ 400 / 8
⇒ 50 m
Question 5
A car going ……………… of the car
Answer
⇒ 0 = 7 x 7 + 2 x a x 10
⇒ a = -49 / 20
Friction Force = ma
=- 49 x m / 20
⇒ – m x 98 / 40
or⇒ – m x 9.8 / 4
⇒ – m g / 4
which is equal to one fourth of car
Question 6
A fire man ……………. man
Answer
given u R = 720 N
page number- 266
Question 7
a block placed ……………. static friction
Answer
Question 8
a block rest ………….the plane is …..
Answer
Question 9
a block of mass 0.05 kg ………………of the block
Answer
when block slide without acceleration then
Question 10
a body is in …………. find the acceleration
Answer
when body is just to slip
Question 11
A body slide ………………. bottom of the plane .
Answer
acceleration of block
