A particle moves in a straight line with a constant acceleration of 1.45 m/s2 for 6s, zero acceleration for the next 5s, and a constant decceleration of 0.56 m/s2 for 4s. Knowing that the particle starts from the origin and that its velocity is 19.95 m/s during the zero acceleration time interval. Determine the distance (in meters) travelled by the particle after 15 seconds. Round off your final answer to three decimal places.
A stone is thrown vertically upward with an initial speed of 20 m/s. When it returns, it falls into a hole that is 10.0 m deep. How long (in seconds) is the rock in the air, from the instant it is tossed until it hits the bottom of the hole? Use -9.80 m/s2 for the local acceleration due to gravity and assume no significant air resistance.
