Abasketball player wishes to make a stunning last-second basket. with .8 seconds on the clock, she wants the ball to enter the hoop (height 3.05m) as time expires in the game. she shoots the ball with an initial speed of 7 m/s, from 2.1 meters above the ground.
1. at what angle (from the horizontal) does she shoot the ball?
2. draw qualitatively accurate position, velocity, and acceleration graphs for both dimensions of the ball's motion while it is in flight.

What challenges did you encounter during the circuit training program?

Use the table to answer question 22 23 and 24.

For problems 1-3, consider a simple dc brush motor with a permanent magnet stator. with an an consider a simple dc brush motor with a permanent magnet ae supply voltage of 100 v, the no-load speed of the motor is 1000 rpm. this motor can provide a torque of 1.9 n-m at 800 rpm drawing a current of 2 a current are both zero at no load.) 1. with an armature supply voltage of 100 v, the motor is operated at 900 rpm. what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input? what is the energy efficiency of the motor? with an armature supply voltage of 100 v, the motor is operated at 1100 rpm (where it acts as a generator). what torque input is required? what mechanical power is required what current is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. with an armature supply voltage raised to 120 v, the motor is operated at 1000 rpm. what is the no-load speed? what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input what is the energy efficiency of the motor? 3.
