Avehicle traveling at 65 mph rounds a curve on a level grade. the driver sees a truck overturned across the roadway at a distance of 350 feet. if the driver is able to decelerate at a rate of 10 ft./s2, at what speed will the vehicle hit the truck? plot result for reaction times ranging from 0.5 seconds to 5.0 seconds in increments of 0.5 seconds. comment on the results.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
