¿En qué tiempo adquirirá un cuerpo una velocidad de 45 km/h si parte con una velocidad de 18 cm/s y se mueve con una aceleración de 4 cm/s2?

the assestment will probley apele with cause and effect

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

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch
