The maximum range of a projecitle fired ...

The maximum range of a projecitle fired with some initial velocity is found to be 1000 metre The maximum height (H) reached by this projectile is:-

A

250 metre

B

500 metre

C

1000metre

D

2000metre

Text Solution

Verified by Experts

The correct Answer is:
A
`R=(u^(2)sin 2 theta)/(g)` At `theta=45^(@)`
`R_("max")=(u^(2))/(g)=1000rArr u=100 m//s`
`rArr h=(u^(2)sin^(2)45^(@))/(2g)=(10000)/(2xx10xx2)=250m`

    The horizontal range (R ) of a projectile becomes (R + 2 H) from R due to a wind in horizontal direction. Here H is the maximum height reached by the projectile. What constant horizontal acceleration is imparted by the wind ?

    " Maximum height attained by an oblique projectile "(h_(m))

    A rocket is fired upwards. Its velocity versus time graph is shown in the figure-1.131. The maximum height reached by the rocket is:

    If R is the horizontal range for theta inclination and h is the maximum height reached by the projectile, Then maximum range is

    Assertion: The maximum horizontal range of projectile is proportional to square of velocity. Reason: The maximum horizontal range of projectile is equal to maximum height attained by projectile.
