LAns: 4.16 hrs) A boy rides motorbike with velocity of 20 m/s. He accelerates his motorbike
to a velocity of 30 m/s for 5 second. Calculate the acceleration produced in the
motorbike.

Aparticle travels in a circular orbit of radius 21 m. its speed is changing at a rate of 23.1 m/s2 at an instant when its speed is 37.2 m/s. what is the magnitude of the acceleration (in m/s? ) of the particle?

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
