A particle moves so that the displacement is given by s= 5t* +84t°+2t?+5t +10. Determine: Q5(a) (i) the displacement after 3 seconds; (ii) the velocity after 45 seconds; (ii) the acceleration after 3 seconds. (b) The height of a building is 80 m. If a stone is dropped freely from the top of a building, determine the time taken the stone at the ground. Explain the effect on time if the mass of the stone is increased.

F = (C · t²) Q14. As shown in the image below, the force acting on the box is N, where constant C = 10 and t is time in s. Determine the magnitude of the total impulse (in N.s) done by force F to the box during the period from t = 0 to t = 1.5 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F Your Answer: Answer 3 5 4
A police car is traveling at a velocity of 20.0 m/s due north, when a car zooms by at a constant velocity of 47.0 m/s due north. After a reaction time 0.800 s the policeman begins to pursue the speeder with an acceleration of 3.00 m/s^2. Including the reaction time, how long does it take for the police car to catch up with the speeder? Number i Units Vos A VOS North AVP AVOP AVOP Police car catches up with speeder ↑ ap Police car begins to accelerate - Speeder passes police car
Q20. A 2-lb ball B is traveling around in a horizontal circle of radius r₁= 5.8 ft with a speed (VB)₁ = 3.4 ft/s. If the attached cord is pulled down through the hole with a constant speed v₁ = 1.1 ft/s, determine how much time is required for the ball to reach a speed of 14 ft/s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. B 1 (VB)1 Your Answer: Answer Vr units
A basketball leaves a player's hands at a height of 2.20 m above the floor. The basket is 3.05 m above the floor. The player likes to shoot the ball at a 38.0 angle. If the shot is made from a horizontal distance of 6.90 m and must be accurate to +/- 0.23 m ( horizontally), what is the range of initial speeds allowed to make the basket? 0
2. A particle on a damped spring has an acceleration of x = -5x -0.2x. It has an initial position of x(0) m = 2 m and an initial velocity of x (0) = 3. Find the position and velocity at t = 4 s. Assume all values are given to three significant figures. Please use any method learned in class: Trial Solution Method, Euler Method, or Laplace Transformation. Show all work.
