Question # 1

If a body does not rotates then its motion is

Vibratory
rotatory
Translational
none of these

Question # 2

Which one of the following possesses rotatory motion?

The air molecules around the fan
An electric ceiling fan
A mark on one wing of the ceiling fan
The down rod of the ceiling fan

Question # 3

An athlete runs along a circular track of radius 1.2 k m . What are the values of distance and displacement covered by him in one complete round trip?

Distance = 7 k m , Displacement = 7.5 k m
Distance = zero, Displacement = 7.5 k m
Distance = 7.5 k m , Displacement = zero
Distance = 7.5 k m , Displacement = 7.5 k m

Displacement is the shortest distance between starting and ending points of a body while distance is the actual distance traveled by a body.

Question # 4

A car starts from rest and gains a velocity of 22 m s − 1 in 11 seconds. Calculate the acceleration of the car.

2 m s − 2
20 m s − 2
Zero
22 m s − 2

Question # 5

What is the state of a passenger sitting in a moving bus?

uniform motion
dynamic motion
rest
relative motion

Question # 6

An athlete is running with speed of 9.5 m s − 1 . He increases his speed with an acceleration of 0.3 m s − 2 in 5 seconds close to the finishing line. Calculate its final speed after 5 seconds.

9.5 m s − 1
Zero
10 m s − 1
11 m s − 1

Question # 7

A motor boat covers 80 km distance in one hour. Calculate its average speed.

Zero
22.2 m s − 1
20.2 m s − 1
80 m s − 1

Question # 8

A man walks 40 m east and then 70 m north. Let east be along x-axis and north along y-axis. Find its position from starting point.

( 40 ^ i + 70 ^ j ) m
( 40 , 70 ) m
( 40 + 70 ) m
( 70 , 40 ) m

Question # 9

The motion of a truck going west is represented by distance-time graph in the figure. What is the magnitude of velocity of the truck after 10 seconds?

0.8 m s − 1
2 m s − 1 west
Zero
2 m s − 1

Question # 10

The displacement covered by a car during different time intervals is shown in the graph. The velocity of the car from 5 seconds to 15 seconds is 2 m s − 1 . What is its velocity from 10 seconds to 25 seconds?
