A marble with speed 20 cm/s rolls off the edge of a table 80 cm high. How long does it take to drop to the floor?
Problem 1:
A marble with speed 20 cm/s rolls off the edge of a table 80 cm
high. How long does it take to drop to the floor? How far,
horizontally, from the table edge does the marble strike the
floor?
A marble rolls off a tabletop 0.70 m high and hits the floor at
a point 3.5 m away from the table's edge in the horizontal
direction.
(a)
How long (in s) is the marble in the air?
__________________________________________ s
(b)
What is the speed of the marble (in m/s) when it leaves the
table's edge?
__________________________________________ m/s
(c)
What is its speed (in m/s) when it hits the floor?
__________________________________________m/s
Anthony carelessly rolls his toy car off a 78.0-cm-high table.
The car strikes the floor at a horizontal distance of 98.0 cm from
the edge of the table.
(a) What was the velocity with which the car left the table?
(Enter the magnitude.) m/s
(b) What was the angle of the car's velocity with respect to the
floor just before the impact? ° below the horizontal
If an object is projected at a given angle and speed, how long
does it take to reach its maximum height?
Please explain in simplest terms and give an example using units
