g)Supplies are dropped from a helicopter and the distance fallen in time t seconds is given by x=1/2gt2,where g=9.8m/s2.Determine the velocity and acceleration of the supplies after it has fallen for 2 seconds. (5mks)
PART B:ANSWER ONLY TWO QUESTIONS (20 MARKS EACH)
Question Two(20 marks)
a)The velocity of a spring is found to be V=6 sin(3?t).Assuming that the spring is perfect,so that v=(1/k)(dF/dT),where k is the spring constant (known to be 0.5),v the velocity,and F the force operating on the spring,find the force,given that it is 0N initially.(8mks)
b)A ball is thrown in the air so that the height of the ball is found to be s=3t - 5t2.Find;(12mks)
i)The ball's initial velocity when first thrown in to the air;
ii)the time when it returns to the ground;
iii)its final velocity as it hits the ground.
Question Three(20 marks)
a)Find the derivatives of system described by the function y=(4sin 5x)/(5x4) (10mks)
b)Find the partial fractions of (5x+2)/(3x2+x-4) and hence evaluate the integral of
(5x+2)/(3x2+x-4). (10mks)
Question Four(20 marks)
a)Use integration by parts formula and use it to find the integral of
x{x/(x2+1)}dx. (10mks)
b)Find the area enclosed between the x axis and the curve y=x3+2x+x+1 between x=-2 and x=2. (10mks)
