3. +-/1 points ColFunPhys1 3.P.013 My Notes Ask Your Teacher An archer wishes to shoot an arrow at a target at eye level a distance of 48.5 m away. If the initial speed imparted to the arrow is 67.4 m/s, what angle should the arrow make with the horizontal as it is being shot?

The fox jumps with an initial velocity of 8.00 m/s at an angle of 45.0°, beginning the jump 1.96 m from the fence. By how much does the fox clear the fence? Treat the fox as a particle. 5. -/1 points ColFunPhys1 3.P.020 My Notes Ask Your Teacher A baseball player hits a home run over the left-field fence, which is 104 m from home plate. The ball is hit at a point 1.10 m directly above home plate, with an initial velocity directed 34.5° above the horizontal. By what distance does the baseball clear the 3.00 m high fence, if it passes over it 3.05 s after being hit?

Explanation / Answer

Solution,

Given,

Range, R = 48.5 m

Range, R = u^2 sin 2(theta) /g

48.5 = 67.4^2 x sin2(theta) /9.8

sin2(theta) = 0.105

Theta = 3 degrees
