Answer:
volume
Explanation:
volume can also be measured by cubic centimeter
Answer:
7.5s
Explanation:
Given parameters:
Velocity = 30m/s
Deceleration = 4m/s²
Unknown:
Time it takes for the car to come to complete rest = ?
Solution:
To solve this problem, we use the kinematics expression below:
v = u + at
Since this is a deceleration
v = u - at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
v - u = -at
0 - 30 = -4 x t
-30 = -4t
t = 7.5s
B. False.
Because its' *Non infectious*
Hope this helps. ;)
Are you answering a question or asking? You have already seemed to get the answer, A is the correct answer :I
Answer:
a). linear acceleration of the hoop and block = 3.2895 <u>m</u>
s²
c). magnitude of the angular acceleration of the disk pulley = 41.119 <u>rad</u>
s²
d). tensions in the string between the block and disk pulley = 11.842 N
tensions in the string between the hoop and disk pulley = 15.625 N

Explanation:
Start by writing "F=ma" equations for each of the things that moves. Also, since some of the objects (the pulley and the orange sphere) rotate, you should write "τ = Iα" equations (net torque = moment of inertia × angular acceleration) for those. In the end, you should have enough equations that you can combine them and solve for the desired quantities.
First, the hoop. There's no indication that it rotates, so we don't need a "τ = Iα" equation for it; just do "F=ma". The hoop has gravity ((mhoop)g) pulling down, and the tension in the vertical string (call it "T_v") pulling up.
