1. You are on a flat football field, 23.0 m away from a very high wall. You throw a raw egg towards the wall, at an initial speed of 22.2 m/s and an angle of 35.5° above horizontal Assuming frictionless free fall: Does the egg hit the wall, or does it hit the ground first? If it hits the ground first, then calculate how far from the wall the egg hits the ground. If it hits the wall, then calculate how high up the wall the egg hits. (b) The egg hits (the wall or the ground) with a certain velocity, v. Find the magnitude and direction(angle) of v. (a)

Answer 1

Voy vox wall Me 60=35.5 روس initial velocity vo = 22.2m/s @ so, the maximum distance travelled by the egg foot ball ground x=23m d = 4² Sin20 8 this is projectile motion = (2212)² So use the formules of projectile x Sin (2x35.5) motion. lo g=10m/see? - 492.84 x 0.945 = 46.57 m that means egg will het the wall. So. the height of the wall where egg hét the wall. hore? sino (22.2). Sin (35.5) 2 g 2x 10 492.84 X 0.337 - 8.304 m (b) final velocity when egg hit the wall. Voy= Vosino So the final nelocity to 2 Vo sino g vy= Voy - gt = Vo sino 2 Vo sino = -Vosino = 22.2 x sin 35.5 - 12.89 onls dérection downward
