A fox locates its prey under the snow by slight sounds rodents make. The fox then leaps straight into the air and burrows its nose into the snow to catch its next meal. If a fox jumps up to a height of 75 cm, calculate the following. Ignore the effects of air resistance. (a) the speed at which the fox leaves the snow m/s (b) how long the fox is in the air s Supporting Materials Pcast Pcast

A fox locates its prey under the snow by slight sounds rodents make. The fox then leaps straight into the air, and then burrows its nose into the snow to catch its meal. if a fox jumps up to a height of 83cm. calculate how long the fox is in the air. Ignore air resistance.

1.) General Physics Problem Solving a.) A sperm whale can accelerate at about 0.0900 m/s2 when swimming on the surface of the ocean. How far will a sperm whale travel if it starts at a speed of 0.800 m/s and accelerates to a speed of 2.18 m/s? Assume the whale travels in a straight line. b.)

Certain insects can achieve seemingly impossible accelerations while jumping. The click beetle can accelerate at up to an astonishing 380g over a distance of roughly 0.700 cm as it bends its thorax, making the click that bears its name. See, for example, Journal of Zoology, Vol. 167(3), 1972, 319-336. a. Say that a particular beetle achieves an acceleration of 356g over a distance of 0.7 cm. Assuming the beetle jumps directly upwards, at what speed would it leave the ground?...
