Disregarding air resistance, what is the speed of a ball dropped from 12 feet just before it hits the ground? (Use 1 ft = 0.30 m, and use g = 9.8 m/s2.)
About 40 to 44 inches.
What is the angular velocity of a 6-foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for p...
1.75 ft
The formula for position is x = 1/2at2. If we start at a distance of 40 feet, and gravity is 32 feet per second squared. So in this instance: 40 = 1/2 (32) t2 40 = 16 t2 40/16 = t2 2.5 = t2 t = 1.58 seconds
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
Ignoring air resistance (which probably is not safe to do) it would impact at a smidge over 18 seconds from when it was released and be traveling about 580 feet per second.
a. 144 feet b. 96 ft/sec.
No, it would hit slower because gravity on the moon is 1/6 the gravity on earth.
Disregarding air resistance, what is the speed of a ball dropped from 12 feet just before it hits the ground? (Use 1 ft = 0.30 m, and use g = 9.8 m/s2.)
About 124 MPH
About 40 to 44 inches.
4 seconds
If it takes 78 seconds to go 55 feet you are traveling at 0.48 miles per hour.
1.364 seconds to travel 50 feet at 25mph.
whats the weight and shape of the rock it depends on that >:(
5.87 seconds.
