Answer:
Explanation:
From the given information:
The torque produced due to the force can be expressed as:

where;
= torque
F = force exerted
r = lever's arm radius
= 
= 60 N.m
However, equating the torque with the moment of inertia & angular acceleration, we use the equation:
= I∝
60 Nm = I × 120 rad/s²
I = 60 Nm/120 rad/s²
I = 0.5 kg.m²
Answer:
F = 329.27 N
Explanation:
given,
mass of snowmobile = 540 Kg
time = 41 s
intial velocity = 9 m/s
final velocity = 34 m/s
Force = ?
Force is equal to change in momentum per unit time




F = 329.27 N
Force applied to the snowmobile is equal to F = 329.27 N
Answer:

Explanation:
in every 20 minutes the prokaryote divides to produce one of itself .
Mathematically,
20 mins:1 of its kind
x mins :512 of its kind
Where x is the amount of time (in minutes) needed by the prokaryote to produce 512 of its kind.
This implies that,
By cross multiplying we obtain,

We now convert the time in minutes into hours.
Knowing very well that 60 minutes equals an hour, to convert 10240 minutes to hour we divide by 60.
This implies that,

Answer:
A. 69.9m
Explanation:
Given parameters:
Initial velocity = 10.5m/s
Final velocity = 21.7m/s
Time = 4.34s
Unknown:
Distance traveled = ?
Solution:
Let us first find the acceleration of the car;
Acceleration =
v is final velocity
u is initial velocity
t is the time
Acceleration =
= 2.58m/s²
Distance traveled;
V² = U² + 2aS
21.7² = 10.5² + 2 x 2.58 x S
360.64 = 2 x 2.58 x S
S = 69.9m
