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.
