A car whose mass is 1000 kg is traveling at a constant speed of 10 m/s. Neglecting

any friction, how much force will the engine have to supply to keep going the same

speed? (Think Inertia) (Look at the units)

If your accelerator is stuck while driving

What is the closed system equation?

Quiescent air is at 20°C (treat air as ideal gas). A plate of depth 50 cm and width 40 cm has a temperature of 40°C on the top surface. Calculate the heat dissipated from the top surface.

Let v (t) = t^2-3t be the velocity, in feet per second, of an object at time t, in seconds. a) What is the initial velocity? ___ ft/sec b) When does the object have a velocity of zero?

Net force is the sum of all the forces acting on an object. If a spring balance pulls on a body with a force of 10 N, and friction acts on the body in the opposite direction with a force of 1 N, the net force would be 9 N in the direction of the
