Question

Below are the paths of two projectiles fired from the same location at the same time. ' (a) The initial vertical speed of projectile A is greater than the initial vertical speed of projectile B. less than the initial vertical speed of projectile B. equal to the initial vertical speed of projectile B. (b) The initial horizontal speed of projectile A is greater than the initial horizontal speed of projectile B. less than the initial horizontal speed of projectile B. equal to the initial horizontal speed of projectile B. (c) Projectile A spends more time in the air than projectile B. less time in the air than projectile B. the same amount of time in the air as projectile B.

Explanation / Answer

Ques 1

(a) since 'A' has higher maximum height higher than that of 'B', this implies that vertical component of velocity of 'A' should be higher than that of 'B'

(b) similar to (a) part, since the range of 'A' is less than that of 'B' hence it's initial horizontal component of velocity should be less than initial horizontal component velocity of 'B'.

(c) the same amount of time in air will be spent by both

Ques2

(a) since both have the same maximum height hence both have same initial vertical component of velocities

(b) since 'A' has lesser range than 'B' hence 'A:' has lesser initial horizontal component of velocity than 'B'.

(c) 'A' spends same time as 'B'.

Ques 3

(b) less than the initial component of 'B'

c)

More time in air than 'B'.
