please answer both questions.
My Notes Ask Your Teacher asketball star covers 2.55 m horizontally in a jump to dunk the ball. His motion through space can be modeled precisely as at of a particle at his center of mass. His center of mass is at elevation 1.02 m when he leaves the floor. It reaches a maximum height of 1.80 m above the floor and is at elevation 0.950 m when he touches down again. (a) Determine his time...

My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....

My Notes Ask Your Teacher The circuit in the figure below consists of two identical, parallel metal plates connected to identical metal springs, a switch, and a 128-V battery. With the switch open, the plates are uncharged, are separated by a distance d = 7.55 mm, and have a capacitance C = 2.00 pF. When the switch is closed, the distance between the plates decreases by a factor of 0.500 (a) How...
