Two forces are applied to a car in an effort to move it, as shown in the following figure, where F1 = 410 N and F2 = 376 N. (Assume up and to the right as positive directions.)
What is the resultant of these two forces?
If the car has a mass of 3,000 kg, what acceleration does it have? Ignore friction.
If you lie on the ground at night with no cover, you get cold rather quickly. Much of this is due to energy loss by radiation. Estimate the net rate at which your body loses energy by radiation to the night sky under these conditions

Elucidate what was the magnitude of the centripetal acceleration of the rock when it was on the string? What was its speed when it was on the string?
An object glides on a horizontal tabletop with a coefficient of kinetic friction of 0.3. If it comes to rest after 1.3 seconds, what was its initial velocity
In a head-on collision, the car stops in 0.23 {rm s} from a speed of 17 {rm m}/{rm s}. The driver has a mass of 77 {rm kg}, and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fract..
