Question

Maximum height and time of flight for a projectile are H and T respectively .If a constant horizontal acceleration a = g / 4 is imparted to the projectile due to wind ,then its maximum height and time of flight will be

• A. Maximum height and time of flight remains same.
• B. Maximum height increases and time of flight remains same.
• C. Time of flight is increases and maximum height decreases
• D. none of these

Answer 1

The correct option is B Maximum height increases and time of flight remains same.

Maximum height H= $\frac{u^{2}si{n}^{2}a}{9}$

total depend on vertical,verity

intial

which will not be affected by horizontal viler

time of fight =2 $\frac{usin}{9}$

totally depend on intial vertical

speed which will w=be

affected by horizontal acceleration

so

both H &7 will remain

same.

Ranse= 7x horizontal verity

mel vary with time as

there will be acceleration

change final so P

will get be
