From the calculation, the acceleration of the body is 26m/s^2.
<h3>What is motion under gravity?</h3>
When an object is thrown up or down, the motion of the body is influenced by the gravitational pull on the body.
Now;
Given that;
v = 39 m/s
t = 1.5 s
u = 0 m/s
a = ?
v = u + at
v = at
a = v/t
a = 39 m/s/1.5 s
a = 26m/s^2

First solve the potential energy of the biker. using the fomula:
PE = mgh
where m is the mass of the object
g is the acceleration due to gravity ( 9.81 m/s2)
h is the height
PE = 96 kg ( 1120 m ) ( 9.81 m/s2)
PE = 1054771.2 J
then power = Work / time
P = 1054771.2 J / ( 120 min ) ( 60 s / 1 min)
P = 146.5 W
Answer:
12,000,000 boxes
Explanation:
the volume of the room can be found by using the equation for volume of a rectangular box:V=LxWxH
where:
L=2m
W=3m
H=4m
(it doesn't really matter which is which since it is multiplication)
when we multiply our values (2m*3m*4m) we get 24cubic meters
now we need to convert cubic meters to cubic centimeters
each cubic meter is 1,000,000 cubic centimeter we multiply 24 by 1,000,000 and we get: 24,000,000 cubic centimeters (cc)
dividing 24,000,000 by 2 (since each box is 2cc) we get 12,000,000
so, we know we can fit 12,000,000, 2 cubic centimeter boxes in this room
A. Up and to the right
B. Put it in the opposite direction so it won’t go left
