Question

A car of mass 100kg starts from.rest and moving with a velocity of 450m/sec. The force is created by the engine in 10 sec is?

Answer 1

Answer:

m=100kg

u=o

v=450m/sec

t=10sec

Explanation:

force=mass*acceleration

acceleration=450/10=45m/sec^2

f=4500Kg m/sec^2

---------------------------

$Given: \\ </p><p>m = 100kg \\ </p><p>u = 0m/s \\ </p><p>v = 450m/s \\ </p><p>t = 10s \\ </p><p>$

----------------------------

$Force = Mass × Acceleration \\ </p><p>F = m × a \\ </p><p>F = 100 × ( \frac{v - u}{t} ) \\ </p><p>F = 100 \times ( \frac{450 - 0}{10} ) \\ </p><p>F = 100 \times \frac{450}{10 } \\ </p><p>F = 4500N$
