Homework Statement
A toy car of mass 0.5kg is pushed agains a spring so that it is compressed by 0.1m. The spring obeys Hooke's Law and has a spring constant of 50N/m. When the toy car is released, what will its speed be at the instant that the spring returns to its natural length? Assume that...

Two physics students are trying to determine the instantaneous speed of a bicycle 5m from the start of a 1000m sprint. They use a stopwatch to measure the time taken for the bicyble to cover the first 10m. If the acceleration was constant, and the measured time was 4sec...
How do i differentiate b/t an action/reaction force described in Newton's Third Law acting on two different bodies, with the normal force and the weight force acting on the same body.
eg:
Scenario 1:
a bin rest on a table: the weight force of the bin exerts on the table due to gravity, and...
