Answer:
a) 919 mts
b) 392 mts
Explanation:
In order to solve this, we will use the formulas of acceletared motion problems:
We are looking to obtain the initial velocity of the canister right after it was relased, we will use formula (2):
we need to calculate the time the canister takes to reach the ground, we will use formula (1):
in order to know the new height of the rocket we have to use the formula (1) again:
We can calulate the total distance the canister traveled before reach the ground by (2):
So the canister will go up another 76m, so the total distance will be:
The speed of the cart after 3 seconds of Low fan speed is (2) cm/s. This is further explained below.
<h3>What is speed?</h3>
Generally, speed is simply defined as the rapidity of movement or efficiency of operation.
In conclusion, After 8 seconds with the fan set at Low, the cart will have traveled 1 cm/s. After three seconds at medium fan speed, the cart travels at a velocity of two centimeters per second.

Answer:
0.9m/s^2 (yours is 0.87, so choose that)
Explanation:
formula for centripetal acceleration:
v^2/r
to find v, we know that f=1/90s, and r=180m.
v=(2pir)/T
v=(2pi(180))/90
v=12.6m/s
now plug into a=v^2/r
a=(12.6)^2/180
a=0.9m/s^2
