Aconstant force of 10n is applied for 3 seconds to an 8kg object. calculate the change in speed

3.75

Explanation:

F= m×a

F=m×(Vf-Vi)/t

10=8×(change in speed)/3

(10×3)÷8=3.75

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
