Question

1. (a) Identify the kind of motion in the following cases:

A car moving with constant speed turning around a curve. Non - Unulogum.mption
(ii) An electron orbitting around nucleus.
(b) An artificial satellite is moving in a circular orbit of radius 36.000 km Calculate
takes 24 hours to revolve around the earth
2. (a) Define average speed.
A bus travels a distance of 120 km with a speed of 40 km/h and returns with a speed of 30
km/h. Calculate the average speed for the entire journey.
3. Define uniform and non-uniform motion. Write one example for each
4 What does the odometer of an automobile measure? Which of the following is moving faster?
Justity your answer
(1) A scooter moving with a speed of 300 m per minute
(1) A car moving with a speed of 36 km per hour
5. A car travels from stop A to stop 8 with a speed of 30 km/h and then returns back to A with a
speed of 50 km/h. Find
(D) displacement of the car
(i) distance travelled by the car
(m) average speed of the car
6 Velocity-time graph for the motion of an object in a straight path is a straight line parallel to the
time axis
(a) Identify the nature of motion of the body.
(b) Find the acceleration of the body.
(c) Draw the shape of distance-time graph for this type of motion
7. Draw the shape of the distance-time graph for uniform and non-uniform motion of object. A bus of
starting from rest moves with uniform acceleration of 0.1 ms for 2 minutes. Find
(a) the speed acquired
(b) the distance travelled
8. (a) Define uniform acceleration. What is the acceleration of a body moving with uniform velocity?
(b) A particle moves over three quarters of a circle of radius r. What is the magnitude of its
displacement?
9. A bus accelerates uniformly from 54 km/h to 72 km/h in 10 seconds Calculate
(1) acceleration in m/s
() distance covered by the bus in metres during this interval
10. A car moves with a speed of 30 km/h- for half an hour. 25 km/h for one hour and 40 km/h- for
two hours. Calculate the average speed of the car​
