Instructions: Solve the following exercises in a clear and orderly way.Two turtles -A and B- compete to reach the goal first (marked with a flag). Ifboth take the same time, t=120, to reach the goal, determine for each of the turtles: a. The distance traveled. b. The speed. c. The displacement. d. The mean velocity. 1 | |
2 | Acop car begins persecuting a suspect that drives his car at 70km/hr. The cop car travels at 90km/hr and is 70m behind the suspect. Determine the time it will take the cop car to reach thesuspect. | |
3 | A racing car travels at an initial speed of 200km/hr and after 3s its speed is 230km/hr.Determine the race car’s acceleration in this time interval. | |
4 | One of thehighest constructions in the world  is the Petronas twin towers in Kuala Lumpur Malaysia, which measure 452m. Determine the position and velocity of an object that is dropped from restingstate from the top of the building after 8s. |
5 | A baseball is thrown vertically upwards at a velocity of 25m/s. Determine: a. The maximum height it reaches. b. The time  the balltakes to reach its highest point. c. The total time the ball spends in the air until it reaches its initial position | |
6 | If we apply a horizontal force of 35N to move a wooden27kg box along a floor of unknown material and at a constant velocity, determine the kinetic friction coefficient between the box and the floor. |
7 | A sleigh of 20kg of mass is movedthrough a flat terrain that is covered in snow. The static friction coefficient is 0.30, and the kinetic friction coefficient is 0.10. Determine: a. The sleigh’s weight. b. The force neededfor the sleigh to begin moving. c. The force needed for the sleigh to have constant velocity. d. Once in movement, what force should be applied for it to accelerate to 1.2m/s2? | |
