A1500 kg car traveling east at 40 km/hr turns a corner and speeds up to a velocity of 50 km/hr due north. what is the change in the car's momentum?

Change in momentum is

Solution:

The momentum of any body is the product of its mass and the velocity associated with the body and is generally given by:

Now, as per the question:

Mass of the car, M = 1500 kg

The velocity in the east direction,

The velocity in the north direction,

Now, the momentum of the car in the east direction:

Now, the momentum of the car in the north direction:

Change in momentum is given by:

Now,

(Since, )

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
