In this lesson, we will learn how to relate the impulse on a body to the change of momentum of the body.
Q1:
A constant force acted on a body of mass 6 kg. As a result, its speed changed from 37 km/h to 49 km/h. Calculate the magnitude of the impulse of this force on this body.
Q2:
Three forces, Fijk=(−5−2+2)N, Fjk=(−3)N, and Fijk=(−−5−2)N, where i, j, and k are three mutually perpendicular unit vectors, acted on a body for 3 seconds. Find the magnitude of their combined impulse on the body.
Q3:
A constant force acted on a body of mass 𝑚 changing its speed from 9 m/s to 54 km/h. Given that the impulse of the force was 5.82 N⋅s, determine the value of 𝑚.
