A man leaves his house for a cycle ride. He comes back to his house after half-an-hour after covering a distance of one km. What is his average velocity for the ride?

A

`0 km h ^(-1)`

B

`2 km h ^(-1)`

C

`2 km s ^(-1)`

D

`1//2 km s ^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Displacement of man =0
`therefore ` Average velocity `= ("Displacment")/("Time") = `

A man leaves his home early in the morning to have a walk. He arrives at a junction of roads A and B as shown in figure. He takes the following steps in later journies : (i) 1 km in North direction. (ii) Changes direction and moves in North-East direction for 2 sqrt(2) km. (iii) Changes direction and moves Southwards for distance of 2 km. (iv) Finally he changes the direction and moves in South-East direction to reach road A again. Now if roads A and B are taken as X-axis and y-axis ,then visible point representing the graph of y=f(x) Then the value of x at which function f(x) is discontinous

A man is standing on top of a building 100 m high. He throws two balls vertically, one at t = 0 and other after a time interval (less than 2 s). The later ball is thrown at a velocity of half the first. The vertical gap between first and second ball is 15 m at t = 2 s. The gap is found to remain constant. The velocities with which the balls were thrown.
