A block of mass m is released on a smooth inclined plane of inclination theta with the horizontal the force exerted by the plane on the bolck has a magnitude

An object is projected at 36.9 degrees above the horizontal. The potential energy of the object at the top of the trajectory is 144j. What is the kinetic energy at the top?

X- and Y- axes in the standard directions, and units in miles: A car moves from (3,4) to (4,8) on a straight line. Evaluate the distance travelled. Express the displacement very clearly!

A truck of mass 9000kg is moving with speed 18m/s, when the driver decides to stop and applies the brakes. After 6s the truck stops. Assuming that the stopping is with constant deceleration calculate the followin:

a)The distance traveled by the car during stopping
b)The acceleration of the truck
c)The loss of energy due to friction

Wht is a predominant mode of heat transfer in solids ?
