A motorcycle of mass m speeds up from speed v0 to speed vf in a time t. a) Derive an equation for the average force F on the motorcycle. (You'll want to first come up with an equation for the acceleration of the motorcycle in terms of v0, vf, and t.). b) Calculate the force that will accelerate a 210-kg motorcycle from 12.5 m/s to 20.8 m/s in 6.9 seconds. c) how does this force compare with the weight of...
Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...

From the starting point (from rest) a car travels a distance
stotal in a straight line with a constant acceleration. At the
distance stotal the car has reached a speed of vfinal. Determine
how much time this took and the value of the constant acceleration.
Take stotal = 200 m and vfinal = 15 m/s.
1. From the starting point (from rest) a car travels a distance Stotal in a straight line with a constant acceleration. At the distance Stotal...
A disk with a diameter of 0.6 m speeds up from 20 rad/s to 40 rad/s in 5.0 seconds. (a) How many revolutions does it go through? (b) How far does the disk travel? (c) What is the average angular acceleration? (d) What is the average linear acceleration?
You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...
A motorcycle is stopped at a traffic light. When the light turns green, the motorcycle accelerates to a speed of 71 km/h over a distance of 50 m. a) What was the average acceleration of the motorcycle over this distance? (b) Assuming the motorcycle maintained a constant acceleration, how far is it from the traffic light after 3.1 s?
A bus accelerates at 1.7 m/s from rest for 13 s. It then travels at constant speed for 22 s, after which it slows to a stop with an acceleration of magnitude 1.4 m/s2. (a) What is the total distance that the bus travels? km (b) What was its average velocity? m/s eBook
Starting from rest, a car speeds up uniformly to 9.80 m/s in a time of 12.0 s. The car then travels with this speed for 20 seconds before slowing down at a constant rate to a stop in 24.0 seconds. Determine the total distance in meters traveled from start to end. Round your final answer to three significant figures.
What is the maximum speed of the motorcycle? It travels to the east along a long straight road. The acceleration = a = 6.6 - 1.14 t for 0 < t < 5.00 seconds where acceleration is m/s2 At t = 0 the velocity was 2.77 metres per second and the position was 7.52 metres What is the maximum speed? Hint - you have to find the time "t" first then use anti-derivatives to get an equation for the velocity. The maximum...
