Centripetal force is defined as the force required to keep a body moving in a circular path and direct towards the center of a circle.
The dimensional formula of centripetal force is [MLT-2]

The horizontal velocity of a projectile is constant (a never changing in value).
There is a vertical acceleration caused by gravity; its value is 9.8 m/s, down,
The horizontal motion of a projectile is independent of its vertical motion.

- Told you right you need some luck. So, Hard-work will take you till 95 for sure.
- Give your preboards with full on preparation as you would do for your boards.
- You have to get 30 on 30 in your practicals.
- Please do not make any silly mistakes at the board exam.
- Remember , scoring 100 isn’t a day task, it needs continuous effort and daily practice.

| Type of Error | Example | How to minimize it |
| Random errors | You measure the mass of a ring three times using the same balance and get slightly different values: 17.46 g, 17.42 g, 17.44 g | Take more data. Random errors can be evaluated through statistical analysis and can be reduced by averaging over a large number of observations. |
| Systematic errors |
The cloth tape measure that you use to measure the length of an object had been stretched out from years of use. (As a result, all of your length measurements were too small.) The electronic scale you use reads 0.05 g too high for all your mass measurements (because it is improperly tared throughout your experiment). |
Systematic errors are difficult to detect and cannot be analyzed statistically, because all of the data is off in the same direction (either to high or too low). Spotting and correcting for systematic error takes a lot of care.

As you have Force on Left Hand Side, the right hand side quantities also represent force....so at and bt2 represent force.....
but dimensional formula of force is
Force: M1 L1 T(-2)
so, dimensional formula of at and bt 2 is also M1 L1 T(-2)
Means, [aT] = M1 L1 T(-2)
SO, [a] = (M1 L1 T(-2) )/T
so [a] = M1 L1 T(-3)
Same way for b,
bt2 = force
so b= force/t2 = M1 L1 T(-4)

As you say that y=4sinat + 3cosbt - ct and here y=distance and t=time
when you will find dimension of equation you will get
distance=no unit+no unit+unit of c*time
( ∵ sin and cos is giving definite value which doesn't have any unit )
As we know we can't be able to add two quantity which have different unit or 1 have unit and other is unit less
∴ your equation is wrong and
∴ You will not get unit of a,b & c

The dimension of the units of a derived physical quantity may be defined as the number of times the fundamental units of mass, length and time appear in the physical quantity.

54 {tex}\times \frac{5}{18}{/tex} = 15 m/s
36 {tex}\times \frac{5}{18}{/tex} = 10 m/s
The relative speed of two approaching bodies is the sum of the two speeds.
In this case we have :
Relative speed : 15 + 10 = 25 m/s
Relative distance is 150 m
Time = {tex}\frac{\text{Distance}}{\text{Time}}{/tex}= {tex}\frac{150}{25}{/tex}= 5
Time is therefore 5 seconds

- Find the derivative of the function.
- Set the derivative equal to 0 and solve for x.
- Plug the value you found for x into the function to find the corresponding y value. This is your maximum or minimum point.
