A cart is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 4.0 m/s2. What is the magnitude of the cart's displacement during the first 6.0 s of its motion?
a. 10 m
b. 55 m
c. 102 m
d. 66 m
given
u = initial velocity of 5.0 m/s
a = acceleration of 4.0 m/s2
t = 6.0 s
the magnitude of the cart's displacement is " s "
then using equation is
s = u t + 1/2 a t2
= 5 x 6 + 1/2 x 4 x 62
= 30 + 72
s = 102 m
the magnitude of the cart's displacement is s = 102 m
option " C " is correct.

A ball is thrown straight up with an initial velocity of 19.6 m/s. Assume it experiences a constant acceleration of 9.8 m/s^2 down (due to gravity) throughout the entire motion. The motion we will consider is the one from the time it was thrown upward to the time it returns to its initial height, which will take a total of 4 seconds. (a) find an expression for the ball's acceleration as a function of time (b) sketch the acceleration as...

1. A sports car moving at a constant velocity travels 120 m in 5.0 s. If it then brakes and comes to a stop in 4.0 s, what is the magnitude of its acceleration (assumed constant) in m/s^2 and in g's (g=9.80 m/s^2). 2. A car slows down from 28 m/s to rest in a distance of 88 m. What was its acceleration, assumed constant?

A sports car moving at constant velocity travels 110 m in 5.0 s . 1.)If it then brakes and comes to a stop in 4.3 s , what is the magnitude of its acceleration (assumed constant) in m/s2? 2.)Express the answer in terms of "g's," where g=9.80m/s2. Express your answer using two significant figures.
An airplane in level flight travels horizontally with a constant eastward acceleration of 8.15 m/s2 and a constant northward acceleration of −24.5 m/s2. The airplane's initial velocity has eastward and northward components of 82.5 m/s and −14.5 m/s, respectively. Determine the magnitude of the airplane's displacement from its initial position after 15.5 s. magnitude=?
