Answer:
Its approx location is (5.18,1.9)
Explanation:
Using F( 5,2) = ( xy-1, y²-11)
 = ( 5*2-¹, 2²-11)
 = (9,-5)
 = so at point t=1.02
 (5,2)+(1.02-1)*(9,-5)
 (5,2)+( 0.02)*(9,-5)
 (5+0.18, 2-0.1)
 = ( 5.18, 1.9)
 
        
             
        
        
        
Answer:
Acceleration due to gravity is 20  
 
So option (E) will be correct answer
Explanation:
We have given length of the pendulum l = 2 m 
Time period of the pendulum T = 2 sec
We have to find acceleration due to gravity g 
We know that time period of pendulum is given by 



Squaring both side


So acceleration due to gravity is 20  
 
So option (E) will be correct answer.
 
        
             
        
        
        
 <span>(a) 
Taking the angle of the pitch, 37.5°, and the particle's initial velocity, 18.0 ms^-1, we get: 
18.0*cos37.5 = v_x = 14.28 ms^-1, the projectile's horizontal component. 
(b) 
To much the same end do we derive the vertical component: 
18.0*sin37.5 = v_y = 10.96 ms^-1 
Which we then divide by acceleration, a_y, to derive the time till maximal displacement, 
10.96/9.8 = 1.12 s 
Finally, doubling this value should yield the particle's total time with r_y > 0
