Fnet=Fapp
manet=Fapp
Solve for m
m=Fapp/anet
m=100N/4m/s^2
so mass must equal 25kg
Assuming this is a frictionless surface

Answer:
20.45%
Explanation:
The probability that the student got a B is
Now, how many students are there in total?
The answer is
How many students got a B?
The answer is
therefore, the probability that the student has got a B is
Hence, the probability that a student has got a B is 20.45%
We use the formula
to find the initial velocity
We have:
Initial velocity (u) = 12 m/s
Acceleration (a) = 14 m/s²
Distance (s) = 48 meters
We are looking to find the final velocity (v)
Substituting these values into the formula, we have:
v² = 12² + 2(14)(48)
v² = 144 + 1344
v² = 1488
v = √1488
v = 38.57 m/s
