F = M A = (20) (10) = 200 newtons
You can calculate this with Newton's Second Law:force = mass x acceleration
196 newtons would be required.
100N
98 newtons.
240N causes= 150a xN causes= 100a X= 240*100\150 = 160N
The idea here is to use Newton's Second Law: F=ma, that is, force = mass x acceleration. Replace the numbers you know - I assume the acceleration is in meters/second2 - and solve for the one you don't - in this case, the mass.
acceleration
total mass = force / acceleration = 99 / 1.5 = 66 kilograms>66 - 10 = 56 kilograms
F = mg + ma F = (1200)(9.8) + (1200)(0.90) F = (1200)(9.8 + 0.9)
F = ma = 45 x 5 = 225 Newtons
The force required is 15 Newtons.
648 N
answer is (D) 120N
150
Just apply Newton's Second Law.
5,400
45,872
5,400 N.
44,896 N
38,064 N
First the acceleration should be 3ms^-2....not 3 ms2...now the force will be 50*3=150 newton...
