1-
a high powered projectile is fired horizontally from the top of a cliff at a speed of 638.6 m/s. determine the magnitude of the velocity (in m/s) after 5 seconds.
take gravitational acceleration to be 9.81 m/s2.
2-
a man throws a ball with a velocity of 20.9 m/s upwards at 33.2° to the horizontal. at what vertical distance above the release height (in metres) will the ball strike a wall 13.0 m away ?
take gravitational acceleration to be 9.81 m/s2.
3-
a particle is moving along a straight path and its position is defined by the equation s = (1t3 + -5t2 + 3) m, where t is measured in seconds. determine the average velocity (in m/s) of the particle when t = 5 seconds.
4-
a particle has an initial speed of 26 m/s. the particle undergoes a deceleration of a = (-9t) m/s2, where t is measured in seconds. determine the distance (in metres) the particle travels before it stops. when t = 0, s = 0.

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ∆t. the resistance of the coil is r, and the total charge is q = i∆t, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly “swiped” past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be “swiped” through the reader at exactly the right speed? why or why not?
