Question

A cricketer can throw a ball to a maximum horizontal distance of 100 m. With the same effort, he throws the ball vertically upwards. The maximum height attained by the ball is

• A. 100 m
• B. 80 m
• C. 60 m
• D. 50 m

Answer 1

The correct option is D 50 m

$R_{max}=\frac{u^2}{g}=100m(when\theta ={45}^{\circ })\therefore u^2=100\times 10=1000H_{max}=\frac{u^2}{2g}=\frac{1000}{2\times 10}=50metre.(when\theta ={45}^{\circ })$
