An object of mass 1 kg is traveling with a constant speed of 10 m/s in the positive x-direction.
Consider case 1 in which the object above comes to a stop in 1 second.
Consider case 2 in which the same object comes to a stop in 10 seconds instead of 1 second.

Which case had the bigger change in momentum?

a. case 1

b. case 2

c. both cases have the same change in momentum

d. it cannot be determined

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Asystematic approach to problem solving is called a (an)
