Answer:
255 m/s
Explanation:
From the question,
F = ma.................................. Equation 1
Where F = Force, m = mass, a = acceleration.
Make a the subject of the equation
a = F/m............................. Equation 2
Given: F = 100 Newton, m = 4 kg.
Substitute these values into equation 2
a = 100/4
a = 25 m/s²
But,
a = (v-u)/t...................... Equation 3
Where, v = Final velocity, u = initial velocity, t = time
Given: u = 5 m/s, t = 10 s
Substitute into equation 3
25 = (v-5)/10
v-5 = 25×10
v-5 = 250
v = 250+5
v = 255 m/s
