The stopping distance d is the distance a vehicle will travel from the point when the
brakes are fully applied to when it comes to a
complete stop. A racecar with a combined
mass m of 25 kg with the driver is traveling
along a racetrack at a velocity v of 100 m/s.
The coefficient of friction u between wet
asphalt and rubber is 0.20, while the
coefficient between dry asphalt and rubber
can reach 0.90. Which of the following
statements is true about the stopping
distance assuming friction does all the work
for stopping the car?

b) phosphorus pentoxide

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
