1 .Bicyclist A starts with initial
displacement zero and moves with velocity 3m/s.At the same
time: bicyclist B starts from a
point with displacement 200m and moves with velocity -2m/s When does A meet B and where are they when this happens?
2.The initial displacement of a body moving
with a constant velocity 5m/s is -10m .When does the body
reach the point with displacement 10m? What distance does the body cover
in this time?
3. A mass has an initial velocity of
10m/s .It moves with acceleration -2.00 ms-2 .When will it have zero
velocity?
4.Object A starts from the origin with
velocity 3m/s and object B starts from the same place with velocity 5m/s , 6
seconds later. When will B catchup with A?
5.An object moving in a straight line
has a displacement-time graph as shown in figure
a Find the average speed for the trip. Find the average velocity for the trip.6. What do you mean
by Physical dimension and What are its Uses?
6.Draw roughly
velocity-Time graph for an an object moving with constant velocity.
7.Draw roughly
distance –time for an object which is at rest.
8.E, m, L, G denote
energy, mass, angular momentum & gravitation constant respectively. Then
what willbe dimensions of EL2
/m5G2?
9.If the speed of
light (C), acceleration due to gravity(g) and pressure (P) are taken as
fundamental units, then find dimensions of gravitational constant (G)
10.what are the
different types of Errors and how it could be minimised.
11.Derive equations of
motion by using calculus
12.A mass starts
out from O with velocity 10m/s and continues moving at this velocity for 5s.
The velocity is then abruptly reversed to -5m/s and the object moves at this
velocity for 10 s. For this motion find:
a) the change in
displacement
b) the total
distance travelled
c) the average
speed
d)the average
velocity
