Explanation:
It is given that there is distance time graph. The slope of any distance time graph will give the speed or velocity of the object.
In the context, it is seen that there is a point in the distance - time graph. And the values of the point in the graph is (4,15).
Now here, the distance is plotted in the ordinate or the vertical y-axis while time is plotted in the abscissa or the horizontal x-axis.
Thus the point (4,15) tells us that the object has traveled 15 units in time equal to 4 seconds.

Explanation:
trying to find the inetria magnitude of the wheel
Assuming the cart rests on a perfectly smooth and horizontal surface, then we can apply Newton's second law,
F=ma => a=F/m
Acceleration, a = Force/mass = 16 N / 8 kg = 2 m/s^2
Answer:
a = - 0.3376 g's
Explanation:
The sports car has a constant speed when travelling. Covered 164 m in 13.77 s. Thus, speed = 164/13.77 m/s
It brakes and now comes to a stop in 3.6 s.
Thus final velocity = 0 m/s
Formula for acceleration is;
a = (v - u)/t
a = (0 - (164/13.77))/3.6
a = -3.308 m/s²
In terms of g's", where 1.00 g = 9.80 m/s², we have;
a = -3.308/9.8 g's
a = - 0.3376 g's
