Issues and problems about different types of movements for students of Physics.
An object is moving with constant velocity 20 m/s in the positive direction of axis x for 50 s. Then the object is moving in the negative direction of axis x with constant speed 10 m/s for 70 s. Find the final position of the object and find the total traveled distance.
Initially the distance between a cat and a mouse is 200 m. The mouse starts to running away with a speed of 8 m/s. Ten seconds after the cat starts running with a speed of 12 m/s in the same direction that the mouse. After what time will the cat catch the mouse?
Two people are running in the same direction with constant velocities. The first person’s velocity is 12 m/s and the second person’s velocity is 15 m/s. If the initial distance between them is 180 m. After what time will the second person pass the first?
A jet lands on an aircraft carrier at a speed of 140 mi/h.
a) What is its acceleration (assumed constant) if it stops in 2.0 s due to an arresting cable that snags the jet and brings it to a stop?
b) If the touches down at initial position 0 m, what is its final position?
A man was driving his car from his office to his home at 50 mph. Thirty minutes later he realized that he forgot some important documents at the office. What constant speed he should drive the car so that he can return to the office within 12 minutes?
A driver is moving with constant velocity from point A to point B, then with constant velocity of 16 m/s from point B to point C. Knowing that the distance between A and B is the same than between B and C and equal to 10 000 m. What was the velocity between A and B points? (The traveled time has been 0.45 hours).
A car is moving with a constant speed of 72 mph from point A to point B, then its speed is 60 mph between B and C. Knowing that the distance between A and B is 5 km and the distance between B and C is 7 km: What are the total traveled time and the average speed?
Date: 1 mile = 1609 m.
An object is moving with constant velocity along axis x. The initial position is and the final position of the object is . Which is its velocity if the traveled time is 4 s?
An object is moving with a velocity of 23 m/s in the positive direction of axis x. The final position of the object is . Which was the initial position if the traveled time is 5 s?
An object is moving with a velocity 10 m/s in the negative direction of axis x. The object is initially at point A with coordinate . Find the position of the object at 5 s.
