Answer:
a = 0.01 [m/s²]
Explanation:
To solve this problem we must use Newton's second law, which says that the sum of forces on a body is equal to the product of mass by acceleration.
ΣF = m*a
where:
F = forces = 10 [N]
m = mass = 100 [kg]
a = acceleration [m/s²]
10 = 100*a
a = 0.01 [m/s²]
Answer:
L = V × I × t
P = V × I then
P = L/t
P = 64000J/200s= 320W
answer : P = 320 W
