Question

A 100 Kg scooty acqire velocity of 45 m/s
to 60 m is in 5 seconds. find the force
applied in this case.​

Answer 1

Answer:

If you know that acceleration is constant, you can solve for it without time if you have the initial and final velocity of the object as well as the amount of displacement. Use the formula v^2=u^2+2as where v is the final velocity, u is the initial velocity, a is acceleration, and s is displacement.

Answer 2

Answer:

9th std book contains the formula

f =ma

force = mass x acceleration

Acceleration = V/T ( velocity ÷ time )

here acceleration = 45 ÷ 5 = 225

therefore force = 100 x 9 = 900 newton
