A mass of 5 kg slides across a frictionless table with an initial velocity of 10 m/s. The wind starts to blow in the direction the mass is moving causing it to accelerate at a constant rate. After 2 seconds,
the mass is moving at a velocity of 15 m/s. What is the acceleration of the mass?

Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
