A cricket fielder can throw the cricket ball with a speed vo. If he throws the ball while running with speed u at an angle θ to the horizontal, find (a) the effective angle to the horizontal at which the ball is projected in air as seen by a spectator. (b) what will be time of flight? (c) what is the distance (horizontal range) from the point of projection at which the ball will land?

Q. A cricket fielder can throw the cricket ball with a speed $v_o$. If he throws the ball while running with speed u at an angle $\theta$ to the horizontal, find

(A) the effective angle to the horizontal at which the ball is projected in air as seen by a spectator.

(B) what will be time of flight?

(C) what is the distance (horizontal range) from the point of projection at which the ball will land if the time of flight is $\frac{2v_0\sin \theta }{g}$ ?

(D) find $\theta$ at which he should throw the ball that would maximise the horizontal range as found $\frac{v_0}{g}[2u\sin \theta +v_0\sin 2\theta ]$

(E) how does for maximum range change if $u>v_o,u=v_o,u<v_o$ ?

(F) As for maximum range change, if $u=v_0,\theta ={60}^{\circ };u>v_0,{\theta }_{max}=\frac{\pi }{2};u=v_0,\theta ={60}^{\circ }$.
How does compare with that for $u=0(i.e{.45}^{\circ })$

Q. A cricketer can throw a ball to a maximum horizontal distance of $100m$. The speed with which he throws the ball is (to the nearest integer):

Q. A cricketer can throw a ball to a maximum horizontal distance of $100$m. The speed with which he throws the balls is?(to the nearest integer)

Q.

A cricketer can throw a ball to a maximum horizontal distance of 100 m. The speed with which he throws the ball is (to the nearest integer)

Q.

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