Question on: WAEC Physics - 2007
An external force of magnitude 100N acts on a particle of mass 0.15kg for 0.03s. Calculate the change in the speed of the particle
A
50ms-1
B
25ms-1
C
20ms-1
D
5ms-1
Ask EduPadi AI for a detailed answer
Correct Option: C
a = (\frac{F}{m} = \frac{100}{0.15} = 666.7)
v = u + at
= 0 + 66.7 x 0.03
= 20m/s2
