Question

The maximum range of a projectile is 100 m . The maximum height reached by it is (A)  100 m  (B) 25 m  (C) 200 m  (D)  75 m

R max =(u2g=100 m The range of the projectile is maximum for the angle of projection θ =45/°) . When the range is maximum the height attained by a projectile is, H=(u24/ g)=(100/4)=25 m

Q. The maximum range of a projectile is $100 m$ . The maximum height reached by it is

$100 m$

$25 m$

$200 m$

$75 m$

$R_{m a x} = \frac{u ^{2}}{g} = 100 m$
The range of the projectile is maximum for the angle of projection $θ = 4 5^{\circ}$ .
When the range is maximum the height attained by a projectile is,
$H = \frac{u ^{2}}{4} g = \frac{100}{4} = 25 m$

Q. The maximum range of a projectile is 100m . The maximum height reached by it is

100m

25m

200m

75m
