Under what condition the magnitude of average velocity is equal to the average speed?

A

51 ft

B

600ft

C

210ft

D

less than 20 mi.

Text Solution

Verified by Experts

The correct Answer is:
C
`v=(v_1+v_2)/2`
v=1/2(23+58) mi/hr . V=40.5 mi/hr
v=40.5 x `"5280 ft./min."/"3600 sec./hr."` =59.41 ft/sec.
X=59.4 ft./sec. x 3.5 sec X =208 ft .

Under what condition is the magnitude of the average velocity of a particle moving in onbe dimension smaller than the average speed over same time interval?

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

Can a body have a. Zero instantaneous velocity and yet be accelerating? b. Zero average speed but non-zero average velocity? c. Negative acceleration and yet be speeding up? d. Magnitude of average velocity be equal to average speed ?

The magnitude of average velocity is equal to the average speed when a particle moves:-

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

Under what condition is the average velcity equal to instantneous velcity ?

Which of the following statements is incorrect? (i) Average velocity is path length divided by time interval. (ii) In general, speed is greater than the magnitude of the velocity. (iii) A particle moving in a given direction with a non-zero velocity can have zero speed. (iv) The magnitude of average velocity is the average speed.

Statement-1: Magnitude of average velocity is equal to average speed, if velocity is constant. Statement-2: It is possible when the direction of motion keeps changing.
