Question

A 20 kg truck drives in a circle of radius 4 m at 10m/s. What causes

Answer 1

Answer:

Normal force

Explanation:

• The force is centipetral force

Calculating :-

• Mass=m=20kg
• Radius=r=4m
• Velocity=10m/s=v

We know

$\boxed{\sf F_c=\dfrac{mv^2}{r}}$

$\\ \sf\longmapsto F_c=\dfrac{20(10)^2}{4}$

$\\ \sf\longmapsto F_c=\dfrac{20(100)}{4}$

$\\ \sf\longmapsto F_c=\dfrac{2000}{4}$

$\\ \sf\longmapsto F_c=500N$
