Question

An athlete jump at a an angle of 30 degree with a maximum speed of 9.4 m/s .suggest an angle by which the athlete can attain the maximum range​

Answer 1

Answer:

We know that,

Range R=  $\frac{u^2sin2x}{g}$

There will be maximum range when sin2x=1

=> Sin2x = Sin 90

=> 2x=90

=> x = 45

Therefore for any trajectory maximum range can be attained only at 45 degrees.
