Question

A car of mass 1500 kg is moving with constant velocity 10 m/s. Calculate the force

required to move this car ​

Answer 1

Answer:

0.8 is the force

Answer 2

Mass (m) = 1500 kg

Velocity (v) = 10m/s

$\large{\underline{\sf{\red{To \: Find-}}}}$

Force = ?

$\large{\underline{\sf{\red{Solution-}}}}$

Here,

[ When An Object Moves with Constant Velocity, it posses K.E (Kinetic Energy) ]

$\boxed{\sf\blue{★ \: K.E = \frac{1}{2} m {v}^{2} }} </p><p>★$

Here,

m = 1500kg

v = 10m/s

Placing Values,

$\implies\sf{K.E = \frac{1}{2} \times 1500 \times {10}^{2}</p><p> </p><p>\implies\sf{K.E = \frac{1}{2} \times 1500 \times 100}} \\ </p><p></p><p> </p><p></p><p></p><p>$

$\implies\sf{K.E = \frac{1}{2} \times 150000} \\ \\ </p><p></p><p>\implies\sf{K.E = \frac{\cancel{ \frac{1}{2} }} \times {\cancel {150000}}}</p><p></p><p>$

$\boxed{\leadsto\sf\red{★ \:K.E =75000 \: N}} \\ </p><p> \\ </p><p></p><p> </p><p> </p><p>\large{\underline{\sf{\red{∴ \: Force \: Is \: 75000 \: Newton.}}}} </p><p>$
