Q. A worker drops a wrench from the top of a tower 61.0 m tall. With what velocity does the wrench strike the ground? (Assume the positive direction is upward.)

Q. A horizontal force of 197 N pushes a 14 kg block up a frictionless incline that makes an angle of 65° with the horizontal.

(a) What is the normal force that the incline exerts on the block?

(b) What is the acceleration of the block? (Hint: assume up the block as the positive direction.)
