b. Find the velocity and acceleration (as vectors, and also their magnitudes), and draw the corresponding velocity What is the dimensional formula of velocity gradient? Differentiate between speed and velocity. The equation of the velocity versus time of a body undergoing constant acceleration is a...
Why would it be a poor idea to have the back of your hand up against the outfield wall when you catch a long fly ball? Why can a batter hit a pitched baseball further than a ball tossed in the air by the batter? Why don't balls bounce as high during the second bounce as...
The special theory of relativity was proposed by Einstein and the concept of relativistic mass is being studied under the special theory of relativity concepts. Relativistic mass m is the mass of a body that changes with the speed of the body as this speed approaches close to t...
it consists of a small mass projectile and a large mass attached to a fixed support with a string like a pendulum when the projectile strike and get embedded in the pendulum, the pendulum rises up to a certain height and by measuring the height we can estimate the speed of the ...
