There are two horizontal forces on the 2.0 kg box in the overhead view of Fig. 5-39 but only one (of magnitude F1 = 20 N) is shown. The box moves along the x axis. For each of the following values for the acceleration ax of the box, find the second force...

A proton (mass ) is being accelerated along a straight line at in a machine. If the proton has an initial speed of and travels 3.5 cm, what then is (a) its speed and (b) the increase in its kinetic energy?

an initially stationary block of mass m on a floor. A force of magnitude 0.540mg is then applied at upward angle of 16. What is the magnitude of the acceleration of the block across the floor if (a)Us=0.6 and Uk=0.5 and (b)Us=0.4 and Uk=0.3 ?

A 1100 kg automobile is at rest at a traffic signal. At the instant the light turns green, the automobile starts to move with a constant acceleration of 3.0 m/s2. At the same instant a 2800 kg truck, traveling at a constant speed of 8.0 m/s, overtakes and...
