1) A particle moves along the x axis according to the equation x(t)=3t - 2t+3, where x is in meters and t is in seconds. a) what is the particle position at t = 2s? b) what is the particle displacement between t = 4s and t = 2s? c) what is the particle average velocity between t = 4s and t = 2s? d) what is the particle velocity as a function of f? e) what is the particle velocity at t=3s? f) what is the particle average acceleration between t=3s and t = 1s? g) what is the particle acceleration as a function of t? h) what is the particle acceleration at t=3s? 2) A person applies brake to stop his car. As he breaks down, the velocity of his car decreases at a constant rate (5.0 m/s). If his initial velocity is 20 m/s, what is the car's stopping distance 3) A car moving in a straight line decelerates uniformly at a rate of 4 m/s reaching a speed of 8 m/s after 6 seconds. Find the distance it travels during that time and the speed of car at the moment of deceleration 4) A person applies brake to stop his car. As he breaks down, the velocity of his car decreases at a constant rate (5.0 m/s). If his initial velocity is 20 m/s, what is the car's stopping distance 5) A ball is thrown directly downward, with an initial speed of 8 m/s, from a height of 30m. After what time interval does the ball strike the ground? 6) You throw a ball vertically upward with speed of 7 m/s. When air resistance is negligible, how long does it take the ball to return to your hand? 1) A particle moves along the x axis according to the equation x(t)=3t - 2t+3, where x is in meters and t is in seconds. a) what is the particle position at t = 2s? b) what is the particle displacement between t = 4s and t = 2s? c) what is the particle average velocity between t = 4s and t = 2s? d) what is the particle velocity as a function of f? e) what is the particle velocity at t=3s? f) what is the particle average acceleration between t=3s and t = 1s? g) what is the particle acceleration as a function of t? h) what is the particle acceleration at t=3s? 2) A person applies brake to stop his car.
