Question

A vehicle needs an engine of 7500 W to keep on moving with constant velocity of 20 ms on a surface. The force required for the motion is
a) 375 dyne
b) 375 N
c) 15000 dyne
d) 150000 N
I need it with explaination i will mark you as the brainliest​

Answer 1

Given :

• Power = 7500 W
• Velocity = 20 m/s

To find :

• Force required for the motion

Knowledge required :-

• Formula to calculate force :-

⠀⠀⠀⠀Force = P/v

[Where : P is the power and V is the velocity.]

Solution :

⠀⠀⠀⇒ Force = P/V

⠀⠀⠀⇒ Force = 7500/20

⠀⠀⠀⇒ Force = 750/2

⠀⠀⠀⇒ Force = 375

Force = 375 N

∴ The force required for the motion is a) 375 N.

Know More :-

Force -

• Force is an external push or pull which tends to change the direction, shape of the object.
• It is the product of mass and acceleration.
• Its S.I. unit is newton (N).
• Force = ma

Velocity -

• It is the distance travelled by a body in one second in a particular direction.
• It is a vector quantity.
• Its S.I. unit is m/s.
• Velocity = Displacement/Time
