A toy rocket is launched vertically upwards with acceleration 3.0 m s−2 . The fuel runs out when the rocket reaches a height of 85 m .
a. a Calculate the velocity of the rocket when the fuel runs out.
b. b Determine the maximum height reached by the rocket.
c. c Draw a graph to show the variation of
- i the velocity of the rocket
- ii the position of the rocket from launch until it reaches its maximum height
d. d Calculate the time the rocket takes to fall to the ground from its maximum height.
