Chapter 6: Q 123. (page 383)

The projectile is fired at an angle of 25掳 to the horizontal with an initial speed of 500meters per second. Find the range R and height H.

Short Answer

Expert verified

The range is 39路08and height is218773路6.

Step by step solution

01

Step 1. Given information .

Consider the given initial speed that is 500meter per second and 胃=25掳.

02

Step 2. Formula used.

The formula used to find range R isR胃=谓o2sin2胃gand to find height H isH胃=谓o2sin胃22g.

03

Step 3. Finding the range and height.

Substitute the values 谓o=500and 胃=25掳in the formula .

R胃=谓o2sin2胃gR胃=5002脳sin50掳9路8R胃=250000脳0路7669路8R胃=39路08

Further simplify.

H胃=谓o2sin胃22gH胃=250000脳0路422622脳9路8H胃=218773路6
