Answer:
1. <u>Average velocity</u>
When t=4
i. [4, 4.1]
= y(4.1) - y(4) / 4.1 - 4
= 275 - 16(4.1)^2 - 275 - 16(4)^2 / 0.1
= 275 - 16*16.81 - 275 - 16(16) / 0.1
= 6.04 - 19 / 0.1
= -12.96 /0.1
= -129.6
ii. [4, 4.05]
= y(4.05) - y(4) / 4.05 - 4
= 275 - 16(4.05)^2 - 275 - 16(4)^2 / 0.05
= 275 - 16*16.40 - 275 - 16(16) / 0.05
= 12.6 - 19 / 0.05
= -6.4 / 0.05
= -128
iii. [4, 4.01]
= y(4.01) - y(4) / 4.01 - 4
= 275 - 16(4.01)^2 - 275 - 16(4)^2 / 0.01
= 275 - 16*16.08 - 275 - 16(16) / 0.01
= 17.72 - 19 / 0.01
= -1.28 / 0.01
= -128
b. Instantaneous velocity
y = 275 - 16t^2
dy/dx = -32t
Considering t = 4
Instantaneous velocity after 4 seconds = -32(4)
Instantaneous velocity after 4 seconds = -128
