1.a car goes off a cliff horizontally at 49 m/s and falls for 5 seconds
a. what us the vertical speed of the car after 5 seconds?
b. what is the horizontally speed of the car after 5 seconds ?
c. what is the actual speed of the car after 5 seconds ?
2.a golfer wants to drive a golf ball a distance of 120 m. if the 3-wood launches the ball at 12 degree above the horizontal. what must be the initial speed of the ball to achieve the required distance ?
3. a place kicker must kick a football from a point of 28 m from the goal and the ball must clear the crossbar, which is 3 m high. when kicked, the ball leaves the ground with a speed of 25 m/s at an angle of 45 degree to the horizontal.
a. by how much does the ball clear of fall short of clearing the crossbar?
b. does the ball approach the crossbar while it still rising or falling ?
8. flash throws a ball into the air as hard as he can and then runs as fast as he can under the ball in order to catch it. if his maximum speed in throwing the ball is 15 m/s and his best time for the 50 m distance is 5 seconds, how high does the ball raise and at what angle did he shoot i?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
