The car has an initial velocity  of 23 m/s and a final velocity
 of 23 m/s and a final velocity  of 0 m/s. Recall that for constant acceleration,
 of 0 m/s. Recall that for constant acceleration,

The car stops in 7 s, so the acceleration is


 
        
             
        
        
        
Answer:
Explanation:
The cannonball goes a horizontal  distance of 275 m . It travels a vertical distance of 100 m 
Time taken to cover vertical distance =  t , 
Initial velocity u = 0 
distance s = 100 m 
acceleration a = 9.8 m /s² 
s = ut + 1/2 g t²
100 = .5 x 9.8 x t²
t = 4.51 s 
During this time it travels horizontally also uniformly so 
horizontal velocity Vx = horizontal displacement / time 
= 275 / 4.51 = 60.97 m /s 
Vertical velocity Vy 
Vy = u + gt 
= 0 + 9.8 x 4.51 
= 44.2 m /s 
Resultant velocity 
V = √ ( 44.2² + 60.97² )
= √ ( 1953.64 + 3717.34 )
= 75.3 m /s 
Angle with horizontal Ф
TanФ = Vy / Vx 
= 44.2 / 60.97 
= .725
Ф = 36⁰ . 
 
        
             
        
        
        
Electromagnets are used in home appliances quite regularly and are used even in simple home appliances. Common home appliances that use electromagnets are toasters, printers, and microwave ovens. Electromagnets are a certain type of magnet that does not function unless an electrical current flows through it. These appliances create the magnetic field by flowing electricity through certain parts of the appliance.
