Answer:
F=2496 N
Explanation:
Given that,
Mass of SUV, m = 1600 kg
Initial speed, u = 0
Final speed, v = 25 m/s
Distance, d = 200 m
We need to find the net force. Firstly, let's find acceleration using equation of motion.
Net force, F = ma
So, the net force is 2496 N.
Answer:
We have the position vector given in terms of time t. r(t) = t^3*i + t^2*j
To find the velocity vector we have to differentiate r(t) with respect to time.
r'(t) = 3t^2*i + 2t*j
The vector representing acceleration is the derivative of the position vector
r''(t) = 6t*i + 2*j
When time t = 2.
The velocity vector is 3*2^2*i + 2*2*j
=> 12*i + 4*j
The speed is the absolute value of the velocity vector or sqrt(12^2 + 4^2) = sqrt (144 + 16) = sqrt 160
The acceleration vector is 6*2*i + 2*j
=> 12*i + 2*j
The required acceleration at t=2 is 12*i + 2*j and the speed is sqrt 160.

Can I have thx and brainliest?
Answer: D. meter, kilometer
SI or "International System of Unit" is the unit that used in the international organization to make counting easier.
In this case, all of the options are base SI but if you compare them both they are a different unit that can't be converted each other. You can't convert gram into second.
Only option D. meter, kilometer is had the same unit that can be converted.
I believe the correct answer from the choices listed above is option A. When looking for a mathematical relationship between two variables, use a line graph. It relates how one variable affects the other by a linear relationship.
Hope this helps.
