SAMPLE PROBLEMS: 111-SET #1 VECTOR ADDITION‚ SUBTRACTION 01-1 1). A man is able to row a boat at 3 mph in still water. If he rows his boat pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition

Equations of Motion Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla
Premium Acceleration Velocity Kinematics
Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly
