SUBMATH: Displacement, Velocity and Acceleration Assignment

  1. A ball is dropped from the leaning tower of Pisa, at a height of 50m from the ground. The ball is dropped from rest and falls freely under gravity. How long will it be before the ball hits the ground?
  2. A particle starts from rest and has an acceleration function 5−10tm/s2. (a) What is the velocity function? (b) What is the position function? (c) When is the velocity zero?
  3. A passenger jet is beginning its decent to its final destination. If it is at a height of 3,000m and traveling at a rate of 120ms, what should be its angle of decent to arrive in 10 minutes?
  4. Upon ignition, a bottle rocket accelerates at a rate of 4ms2 for 5s before it loses thrust. What is the bottle rocket’s maxmimum height? Neglect air resistance and assume g=10ms2
  5. A cannon is packed with gunpowder and a ball of mass 10kg. The cannon is angled at 30 degrees. When fired, the gunpowder releases 500J of energy, which is all transferred to the cannon ball. Neglecting air resistance and friction within the cannon, how far does the ball travel before hitting the ground? Assume g=10ms2
