You attach a meter stick to an oak tree, such that the top of the meter stick is 2.67 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.311 seconds to pass the length of the meter stick, how high (h0) above the ground in meters was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down?
A suspicious-looking man runs as fast as he can along a moving sidewalk from one end to the other, taking 2.50 s.Then security agents appear, and the man runs as fast as he can back along the sidewalk to his starting point, taking 10.0 s.What is the ratio of the man’s running speed to the sidewalk’s speed?
A daredevil is attempting to jump his motorcycle over a line of buses parked end to end by driving up a 32o ramp at a speed of 40.0 m/s . How many buses can he clear if the top of the takeoff ramp is at the same height as the bus tops and the buses are each 35.0 m long? ~ 10 ~ 7 ~ 4 ~ 12
You are on the roof of a Physics Building, 21 m above the ground. Your physics professor, who is 1.71 m tall, is approaching the building at constant speed of 2.04 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg?
A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, hh, in feet, tt seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)
I took 2.28km and converted it to 2280 meters then divided by 3200 and ended up with .71m/s but it keeps saying that its incorrect. Im not sure where I keep messing up.
