A police car is traveling at 12m/s due east, when it sees a car 20m ahead traveling at a constant velocity of 50m/s due east. After a reaction time of 0.95s the policeman begins to pursue the car with an acceleration of 5m/s2. Including the reaction time, how long does it take for the police car to catch up with the speeder and the distance where they meet? Type the numerical answer before submitting.

A motorcycle, starting from rest, has an acceleration of 2.6m/s2. After it has traveled a distance of 120m, it slows down with an acceleration of -1.5m/s2 until its velocity is 12m/s. Calculate the total displacement.

From the top of a 60m building an object is thrown with a speed of 10m/s and an inclination of 40 degrees. Calculate the final velocity of the object just right before the impact with the ground. You must type your answer below.

Solve the triangle.b = 4, c = 5, A = 75°

The 20 degrees inclined plane has mass 1 of 10Kg and mass 2 of 3Kg. The pulley is 5Kg with a radius of 1.5m. If the coefficient of kinetic friction is 0.1, calculate the magnitude of the linear acceleration of the system.
