Money Miguel, a 95 kg halfback is moving at 4.1 m/a on an apparent breakaway for a touchdown when he was tackled at the goal line by Joey Gonzalez, an 85 kg cornerback running at 5.5 m/s in the opposite direction. a) what was their mutual velocity immediately after the tackle?

b) did mighty Miguel score? explain.

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

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.
