PHYSICS 201 ASSIGNMENT to be submitted during the Trinals

  1.  An airplane travels 640 m down the runway before taking off. If it starts from rest, accelerates and becomes airborne in 8 seconds, determine the final take – off speed.

  2.  The brakes of a truck can decelerate at 3 m/s² Determine the distance that the truck will travel before coming to a stop if it is initially moving at 28 m/s when the brakes are applied.
  3. A station wagon starting from rest is uniformly accelerated and travels 250 m in 50 seconds. Determine the average velocity the acceleration and the final velocity.
  4.  A catapult is used to launched a naval aircraft into the air. If the catapult acts over a distance of 42 m, determine the acceleration which will give the aircraft a speed of 48 m/s during launching. 

    5. Calculate your average speed if you walk 800 m with a speed of 1.5 m/s and then jog  for 1200 m with a speed of 3 m/s.

6.   A  2-g bullet is uniformly accelerated in a rifle barrel 1.2 m long. If the bullet leaves the barrel with a speed of 300 m/s , determine the acceleration and the time of travel of the bullet along the barrel.

Good luck!
