Which units are used to measure both velocity and speed? check all that apply. m/s d/t km/h mph lph

m/s km/h mph

Explanation:

The units above are all used to measure velocity and speed. In fact:

- m/s: this is meters (m) per second (s), this is the SI unit for the speed and the velocity, it used when the distance is expressed in meters and the time is expressed in seconds

- km/h: this is kilometers (km) per hour (h). In this case, the distance is expressed in kilometers while the time taken is expressed in hours. Since

1 km = 1000 m

1 h = 3600 s

We can write a conversion factor between m/s and km/h:

- mph: this is miles (m) per hour (h). In this case, the distance is expressed in miles, while the time is expressed in hours. Since

1 mile = 1.609 km

We can write a conversion factor between km/h and mph:

answer: a. same unit

explanation:

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
