a) Calculate the acceleration of the body
b) What is the force acting on it
c) What is the force at t=1 sec
d) What are the dimension of a
Question: 2
An 8 Kg object is subjected to three forces
a) Find the acceleration of the object.
b) If the object starts from rest from origin, what will be the location after 4 sec
c) What is the magnitude of resultant force and its direction?
d) What fourth force F4 should be applied on the body to make the net resultant force zero
Question 3
Consider a three body system shown in figure below
1) Find the acceleration of the each object
2) Find the contact force between all the objects
Question: 4
Three Block of mass m1, m2 and m3 are connected as shown in the figure below.
All the surfaces are frictionless and strings and pulley are light. Find the acceleration of all the masses
Question: 5
A small block of mass m1= 3 kg is placed at rest on a larger block of mass m2=5 kg .The situation is given in the figure below
The coefficient of friction between the two block is µ=.3
And the horizontal surface is smooth.A constant Force F is applied on the block
Find out the following
a) Find the value of limiting friction between the two blocks
b) What is the maximum acceleration by which the upper block can move
c) What is the maximum value of F at which both the block move together
d) if F=20 N,what is the acceleration of each block and what frictional force is acting between the block
e) What is the normal contact force between the blocks
f) what is the normal contact force between the larger block and the smooth surface
g) if F=40 N,what is the acceleration of each block and what frictional force is acting between the block
h) If the force is applied to the upper block,what will be the minimum force required so that there is relative motion between the block
Given g=10 m/sec2
