The speed limit on the main road through town is currently 55 mph. Drivers approaching that intersection are first able to see the stop sign from 44 meters away. Does that give them enough advance warning to stop before reaching the intersection, if they are going 55 mph? Use braking distance (how much distance a car travels from the time the brakes are applied, until the car comes to a complete stop). Using this information, compute the worst-case stopping distance (number of meters) at this intersection for a vehicle going 55 mph.

Skm/h = %D Part (b) Suppose the speed limit is 79 km/h. How many kilometers per hour would the car need to slow down to be going the speed limit? Numeric : A numeric value is expected and not an expression. As =
The velocity of an object is given by, = u + at V ds dt. where, u is the initial velocity, a is the acceleration, and ₺ is the time in seconds. Solve the differential equation to obtain the displacement, s, given that at t = 0, s = 7 (metres) : 1 if u = 3 ms ¹, a = 2.4 ms 2, calculate the displacements at t = 4.9 seconds. Give your answer to 2 decimal places.

A student witnesses a flash of lightning and then t = 1.5 s later the student hears the associated clap of thunder.Sound travels at 343 m/s in the air. What distance from the student is the lightning strike, in meters? Light travels at 3.0 × 108 m/s in the air. How long, t1, in seconds did it take the light to reach the student's eyes after the lightning strike?
The speed of propagation of the action potential (an electric signal) in a nerve cell depends (inversely) on the diameter of the axon(nerve fiber). If the nerve cell connecting the spinal cord to your feet is 0.9 m long and the nerve impulse is 16 m/s. How long (in s) does it take for the nerve signal to travel this distance ?
You are driving home from school steadily at 97 km/hkm/h for 160 kmkm. It then begins to rain and you slow to 61 km/hkm/h instantly. You arrive home after driving 4.5 hours. How far is your hometown from school? answer using two significant figures.

A quadratic fit is done on a distance versus time graph of an object with constant acceleration using a computer program. The distance is in meters and the time in seconds. The form of the quadratic fit is y (z)= Az + Bz + Cand the fit parameters were found to by A-0.5, B-2 and C-3. What is the acceleration? 1.5 m/s 0.25 m/s 0.5 m/s -2 m/s 1 m/s 3 m/s OO0O C
Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vr
Answer the entire problem set by using kinematic equations. Your answers must be rounded off to two decimal places. If the numerical answer exceeds 1000, do not use a comma as for 1,000. An airplane accelerates down a runway at 4.50 m/s2 for 45.6 s until it finally lifts off the ground. Determine the distance traveled before takeoff.
