Answer:
a = 4/9 m/s^2
Explanation:
We use the kinematics formula for distance (d) covered i accelerated motion:
d = vi t + (1/2) a t^2
and replace d= 2, t = 3 and vi = 0 as per the information given:
2 = (1/2) a (3)^2
2 = (1/2) a (9)
a = 4 / 9 m/s^2
<span>To find the gravitational potential energy of an object, we can use this equation:
GPE = mgh
m is the mass of the object in kg
g = 9.80 m/s^2
h is the height of the object in meters
GPE = mgh
GPE = (0.700 kg) (9.80 m/s^2) (1.5 m)
GPE = 10.3 J
The gravitational potential energy of this can is 10.3 J</span>
The average speed is 8 miles
