List three applications of pressure in our daily lives.

1) Skis have a large area to reduce the pressure on the snow. This ensures that the skis do not sink into the snow too far.

2) The pressure under the studs on the soles of football shoes is high enough for them to sink into the ground, which gives extra grip.

3) A vacuum cleaner has a fan inside that creates a low pressure inside the device. Consequently, air and dirt particles are sucked into the device.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
