60$
10% of 50$ is 5(50/10), so 20% (10% x 2) would be 10 (5$ x 2)
The original 50$ added to the 10$ would make 60$
W = 2J
J = T + 3......T = J - 3
W + T + J = 17
2J + J - 3 + J = 17
4J - 3 = 17
4J = 17 + 3
4J = 20
J = 20/4
J = 5 <=== Jamal is 5
W = 2J
W = 2(5)
W = 10 <== Wilma is 10
T = J - 3
T = 5 - 3
T = 2 <== Tim is 2
Answer: x=5
5x-3 (x-3)= -6 +6x -5
5x -3x +9 =-6 +6 x -5
- Force=0.02N=F
- Acceleration=a=8m/s^2
- Mass=m
