Question

A projectile is projected at some angle from the ground towards east in the absence of air resistance then time period and range of projectile
are T and R. If wind starts blowing towards east with some acceleration, then the new time period
T' and range R' have the relations.
(1) T' > T and R'>R (2) T' > T and R' <R
(3) T' = T and R' <R (4) T' = T and R' >R​

Answer 1

Answer:

T' = T and R' >R​

Explanation:

A projectile is projected at some angle from the ground towards east in the absence of air resistance then time period and range of projectile

are T and R. If wind starts blowing towards east with some acceleration, then the new time period

T' and range R' have the relations.

(1) T' > T and R'>R (2) T' > T and R' <R

(3) T' = T and R' <R (4) T' = T and R' >R​

option 4 is correct T' = T and R' >R​

As time is dependent upon , time to reach upward & come down ward

& wind blow will not impact this.

Hence T' = T

Now wind starts blowing towards east => Speed towards east will keep increasing with the blow speed  Hence with in the same time , Horizontal Distance covered will be more

Hence R' >R​
