Question

A ball is thrown straight up, from 3 m above the ground , with a velocity of 14m/s . Gravity pulls it down. Ignoring air resistance , the distance travelled by the ball with respect to time can be modelled using the equation h= 3+ 14t - 5t², where h is the distance in meters and t is the time in seconds.

a) what is the name of the polynomial represent by the above equation.
i) linear polynomial
ii) cubic polynomial
iii) quadratic polynomial
iv) none of the above

b) after how many seconds does the ball hit the ground.
i) 0.2
ii) 3
iii)1
iv) 2

c) find the maximum height the ball reaches.
i)10m
ii) 12.8 m
iii) 14m
iv) 5m

d) mention the name of the graph in the given equation .
i) ellipse
ii) line
iii) parabola
iv) circle

e) For an nth degree polynomial, what is the maximum number of zeros or roots possible?
i) 0
ii)2n
iii)n
iv)1
