Q. 2. A force of 100N acts on a mass of 25 kg for 5 s .What velocity does it generate?
Given : F=100N. a=acceleration
T=time
M=25kg. M=mass
T=5sec
F=ma
acceleration=mass/force
a=100/25
a=4m/s2
Then
V=u+at
V=0+4×5
V=20 m/s.
Answer thanks
Q. 3. A bullet leaves a rifle with a velocity of 100m/s and the rifle of mass 2.5 kg recoils with a
velocity of 1m/s. Find the mass of the bullet?
To find the velocity generated by the given force acting on a mass, we can use the equation:
Velocity (v) = Force (F) * Time (t) / Mass (m)
In this case, the force is given as 100N, the mass is 25 kg, and the time is 5 seconds. Plugging in these values, we get:
v = (100N * 5s) / 25kg
Now, we can calculate the velocity:
v = 500Nm / 25kg
= 20 m/s
Therefore, the velocity generated by the force of 100N acting on a mass of 25 kg for 5 seconds is 20 m/s.
Newton #2 - Force = rate of change of momentum
so
force * time = change in momentum (impulse)
100 * 5 = 25 * v
A force of 100 newton acts on a body of mass 25 kg for 5 seconds. what velocity does it generate
1.)20m/sec-2
2.)
