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.

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.

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.

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
