Answer 3

w8 dude..

Answer 4

ko everyone hahahha

Answer 5

Vy = 10 -2t
Vx = 8 + 4t
Sy = y-coordinate
Sy = integral of 10-2t = 10t - t^2 + c

dSy/dt = 10 - 2t = 0 for maximum
this is given from the first equation
t = 5
Vy = 0
Vx = 8 + 28
Velocity = 28 m/s in direction x

Answer 6

hmm the book says the answer is (32 m/s)î

Answer 7

sorry will be back later

Answer 8

Thats in the x direction
