PROBLEM 10 A Man driving a Car at 72km/h towards the traffic light, when he is 150m from the traffic light, the light turns yellow. He quickly accelerates at 3ms-2. But after 4s, he decides that he can't make the light in time and suddenly applied brakes. He decelerates uniformly, coming to a stop at the light. Determine his deceleration?​

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
