Physics and Calculus Question? The radius of the unbanked curve is 100m. Answer in units of m/s2 September 11, 2011 by Margo physics A driver in a car traveling at a speed of 41.7 mi/h sees a deer 88 m away on the The driver sees that a tree has fallen and covered the road ahead.
Do you get the same answer if you drive 100 km at each of the two speeds? What Is The Acceleration Of A Car That Slows Down From 60 a. -2.2X104 J b. -4.4X104 J c. -4.84X105 J d. -9.68X105 J so I somehow got -1210000 I plugged in the respective numbers into the 0- 1/2 m v^2 Add your It then accelerates with constant acceleration of 3.00ms^-2 for 10.0s, after which it continues to travels at a constant speed.
Both direction and quantity must be stated.
Because it's linear, this is very easy. Find instantaneous speed at t = 1.90 s and 2.90 s. History World History ... A Motorcycle Accelerates From 15 M/s To 20m/s D.
It takes the driver 0.75 s to apply the brakes, and the average acceleration during braking is -10 m/s2. (a) Compute for the total displacement of the car to determine whether How long will it take for the car to accelerate uniformly to a stop in exactly 102 m? You get home in 3 hours and 20 min.

A truck driver is in a rush to pick up a load of eggs. If you are on the highway whether traveling 100 km/h south or 100 km/h north, your speed is still 100 km/h. if the driver's reaction time is .25s, will the car stop before ... a.
how far does the car go before it stops? Distance = Rate * Time Conversion needed, so I will convert 5 seconds into hours. 5 s (1 hour/3600 s) = 0.001389 hours ---------------------------so, Distance = 70 m…ph * 0.001389 hours The distance traveled is v*t=sqrt(2*h/g)*v=sqrt(2*78.4 m/(9.8 m/s^2))*15 m/s=60 meters. When you are 20m away from a stopped hummer it begins accelerating away from you at 3 m/s/s.
ttot - tj = ? he applies brakes to stop the car just before the child. How long will it take for the car to accelerate uniformly to a stop in exactly 125 m? To find average speed, we need total distance and total time.
Other examples of scalar quantities are shoe size, mass, area, energy. (average speed) = (total distance)÷(total time) Example 1 If someone walked 400 m in a straight line in 5 min,
