A placekicker must kick a football from a point 36.0 m(about 40 yards) from the goal. Half the crowd hopes the ballwill clear the crossbar, which is 3.05 m high. When kicked, theball leaves the ground with a speed of 20.0 m/s at an angle of53.0° to the horizontal. (a) By how much does the ball clear orfall short of clearing the crossbar? (b) Does the ball approachthe crossbar while still rising or while falling?
An unsuspecting bird is coasting along in an easterly direction at 2.00 mph when a strong wind from the south imparts a constant acceleration of 0.300 m/s2 . If the wind's acceleration lasts for 3.40 s , find the magnitude ? and direction ?(measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally travelling in the +? direction and that there are 1609 m in 1 mi . r=3.499m ?= 27.71∘
Now, assume the same bird is moving along again at 2.00 mph in an easterly direction, but this time, the acceleration given by the wind is at a ?=37.0° angle to the original direction of motion, measured counterclockwise from the easterly direction. If the magnitude of the acceleration is 0.300 m/s2 , find the displacement vector ?⃗ and the angle of the displacement ?1 .
Enter the components of the vector, ?? and ?? , and the angle. Assume the time interval is still 3.40 s .
?⃗=???̂+???̂
