Q.1 Solve any FOUR of the following:
a. State equations of motion modify these equations for body falling freely.
b. A meter scale is falling down without slipping from vertical position with 2rad/s. Calculate
acceleration with which it falls.
c. State Newton’s third law of motion. What do you think about cancellation of action &
reaction?
d. Define Ultrasonic and specify its frequency range.
e. Each man pulls load at an angle 300 with horizontal with 2kn. Find work done in 15m
displacement.
f. State Newton’s second law of motion.
Q.2 Solve any THREE of the following:
a. A block of mass 20kg is pulled on a floor by horizontal rope through distance of 20m.
If coefficient of friction between block & floor is 0.2, find work done.
b. Explain magnetostriction method for production of ultrasonic.
c. State the formulae for the tension in the string in case of two bodies attached by a string and
passing over a smooth pulley?
d. A train changes its speed uniformly from 50 km/hr to 100 km/hr in a distance of 500m.
What is its acceleration? Draw VT diagram in above case & calculate distance using VT
diagram.
e. Represent displacement, velocity and acceleration of a particle in S.H.M. for particle starting
from mean position.
Q.3 Solve any TWO of the following:
a. A body accelerating uniformly at 5rad/s2 is found to be rotating at 90rad/s at the end of
12/sec. Determine initial velocity & angle turned during this internal.
b. Explain graphical representation of work done.
c. The second hand of a clock is 6 cm long. Calculate the linear speed of ant sitting a its tip.
