Ken's prediction for december was –5°c. the actual low temperature was 3 degrees higher than his prediction. the actual low temperature in december was ºc. pls

The actual low temperature will be -2°C

Explanation:

We have given that Ken's prediction of temperature in December month is 5°C

And it is given that the actual temperature is 3° higher than the temperature he predicted

We have to find the actual temperature

For finding actual temperature we have to add 3 in predicted temperature

So actual temperature = -5+3 = -2°C

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
