8. The car is traveling at 30 mi/h when the traffic light 295 ft ahead turns yellow. The driver takes 1 s to react before he applies the accelerator. If the car has a constant acceleration of 5 ft/s² and the light remains yellow for 5 s, will the car reach the light before it turns red? How fast is the car moving when it reaches the light? Ans. No. 66.7 ft/s
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Several forces are acting on a bolt as shown in the diagram below. It is desired to determine the resultant of all of the forces acting on the bolt. The axis of the bolt is at a 45° angle with respect to the x-axis. The line of action of force Pis parallel to the x-axis. The magnitudes of the forces and the angles labeled are as follows: P = 35 N S = 60 N T = 31 N a = 15⁰ Q = 53 N 0 = 25⁰ B = 65° y P T S x
P2. A ball is kicked from the origin with an initial speed of v1, = 25.0 m/s, at an angle 0 with the horizontal.
