A driver, driving at a constant speed of 30m/s in a 50 mph zone, is unaware that he is being observed by an approaching police car (coming toward him from the front). At time t = 0, they are 800m apart and the police car has an approach speed of 40 m/s. When will the police officer catch up with the motorist? a) 80 s b) 68.6 s                            c) 11.4 s

Two cars are driving, car 1 has initial position -3500m, initial velocity -55m/s and acceleration +1.25m/s2, car 2 has initial position +4100m, initial velocity -35 m/s and acceleration +0.75m/s2;   a) How much time until they collide? b) What is the x location where they collide, and the final velocity of each car?

A particle moves in such a way that a = 2t + 2 m/s/s, where t is in seconds. Determine the velocity ( m/s ) of the particle after 5 seconds. O 15 O 25 O 30 O 37

Two objects flies towards each other. When the distance between them is 1.3 km their velocities and acceleration are as follows:        vA = 44 m/s , vB  = 24 m/s , aA  = -0.1 m/s2  and  aB = 1.1 m/s2 A third object (C) left object A and moves towards object B with velocity of 43 m/s. Upon reaching B, it then flies back to A and so on until A and B meets. Determine the following:      a. Time it takes for ball A and B to meet      b. Where ball A and B will meet with respect to the initial position of A?      c. What is the total distance travelled by the third object?

1) The motions of a car and a motorbike along a straight road are described by the velocity vs time graph provided below. The two vehicles are initially alongside each other at time t=0 s. The motorbike’s speed is 18.1 m/s and the time T is 59.9  s.  a) what distance has the motorbike travelled between 0 and T (in km)? b) What distance has the car traveled between 0 and T (in km)? 2) Which of these statements is true? a. At T, the car and motorbike are at the same location. b. the acceleration of the car is constant between 0 and T  c. the acceleration of the motorbike is 0 d. the acceleration of the car is 0  3) a)What is the car's average speed for the first T seconds? (in m/s) b) What is the motorbike's average speed for the first T seconds (in m/s)

1.) An acceleration of 90.0 m/s^2 was experienced by a rocket which was launched upward. The acceleration stopped after 10.0 seconds when it run out of fuel . What is the highest speed (m/s) that the rocket experienced?

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.

2. Write the kinematic equations for distance and velocity describing a particle moving in the x-direction with initial position 4m, initial velocity 2m/s, undergoing a constant acceleration of 3m/s² a) x(t) %D b) v(t) =

A distance of 60 meters separates two jetskis at Virginia Beach. Starting at rest, the jetskis accelerate at a constant rate of 0.2 m/s2 towards each other.Starting at a midpoint between the two jetskis, a porpoise is seen swimming from one jetski to the other at a constant speed of 16 m/s. The porpoise continues swimming back and forth between the jetskis until they crash together.a) What is the total distance the porpoise travelled? b) what is the speed of the jetskis when they crash together?
