Which of the following statments must be true for a falling object that has been dropped from rest near the surface of earth.
an object falling near the surface of the earth has a constant acceleration of 9.8 m/s2. this means that the: a) object falls 9.8 m during the first second of its motion. b) object falls 9.8 m during each second of its motion. c) speed of the object increases by 9.8 m/s during each second of its motion. d)acceleration of the object increases by 9.8 m/s2 during each second of its motion. e)force of gravity on the object must be 9.8 n.

To travel at constant speed, a car engine provides 24kw of useful power. the driving force on the car is 600n. at what speed does it travel?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
