A1700 kg car moving at 5.1 m/s is initially traveling north in the positive y direction. after completing a 90° right-hand turn to the positive x direction in 4.1 s, the inattentive operator drives into a tree, which stops the car in 240 ms. what is the magnitude of the impulse on the car (a) due to the turn and (b) due to the collision? what is the magnitude of the average force that acts on the car (c) during the turn and (d) during the collision? (e) what is the angle between the average force in (c)and the positive x direction?

momentum of soft ball three times less than baskey ball

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
