Stopping Distance of a Hot Wheels Car
While the Hot Wheels car collides along with the box and skids to a stop, external forces do an important amount of work upon the car. The force of friction acts within the direction opposite the car's motion and therefore does negative work upon the car. This negative works contributes to a loss within mechanical energy of the car. Actually, if 0.40 Joules of mechanical energy are lost, then -0.40 Joules of work are completed upon the car. As this work is completed, the mechanical energy of the car (within the form of kinetic energy) is transformed within non-mechanical forms of energy like as sound and heat.
The energy to which the human ears are sensitive is named as sound. In general all parts of waves are produced in an elastic material phase, Irrespective of while these are listen
The angular displacement of a body is a function of time and giving by equation h=10+3t+6t square,where t is in seconds.determine the angular velocity, acceleration when t=5seconds
