Question

This projectile is launched on a 3-4-5 slope with an initial velocity v, of 100 feet per second at strikes a wall that is a distance d = 200 feet from the launch point. Find the height hat which the projectile strikes the wall. Report your answer in ft. hmax h

Answer 1

Solution :- Vosine Giren that Vo = 100 ft /see + 4 h se tano = 3 V Coo d - 200 200ft o 36. 8698 and, Vo sino 100 Sin 36. 8 698 59.99 ft/sec Vo los o 10o los 36.86 98 = 80 ft /see Equation of motion for a direction 5x = lat uat t ght? aa= o Mo Acceleration in a Axi d = v cos o t 200 H Ma = vcoso d V Caso so ft/ see v t = 2.5 see

Equation Sy t of Motion for y directions. git Myt + +Bay ft/5² v sinet & It g) t lay=- g = - 32017 11 59.99 x 2.5 – 1 x 32. 1 7405 X2.5 2 49.43 109 ft Answer. h= 49.43109ft at which the projectile sprike the mall
