Question

what is the force acting on a ball of mass 100 gram thrown vertically upwards with a velocity of 36 km per hour at its highest point. Gravity is 10m/s^2​

Answer 1

Since the initial upward velocity was 100 m/s, it will be 90 m/s after one second, 80 m/s after 2 s, 70 after 3, etc, until it comes (briefly) to rest after ten seconds.

Then, after another ten seconds, it should land on your toe 20 s after launch.

You didn’t ask, about the maximum height, but the easiest way to calculate it is to multiply the 10 seconds of ascent by the AVERAGE VELOCITY (which was 50 m/s).

Hope this helps you ☺️☺️✌️✌️❤️❤️

Answer 2

When switch s is open the reading of voltmeter is 12 volt and when the switch has been closed the reading of voltmeter is it volte in that of ammeter is 2 ampere then determine the emf and internal resistance of the battery
