Aspring on the produce scale at the farmers market has a spring constant of 5.2 n/m. a giant bag of apples is hung from the spring and the spring stretches 0.32m. what is the elastic potential energy stored in the spring?

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

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)]

Will you chech and finish these for me, because i am stumped with them.
