A shot-putter throws the shot with an initial speed of 11.2 m/s
from a height of 5.00 ft above the ground. What is the range of the
shot if the launch angle is (a) 24.0 ∘ , (b) 30.0 ∘ , (c) 42.0 ∘
?
Problem 3.29
A shot-putter throws the "shot" (mass = 7.3 kg ) with an initial
speed of 14.5 m/s at a 37.0 ∘ angle to the horizontal.
Part A
Calculate the horizontal distance traveled by the shot if it
leaves the athlete's hand at a height of 2.15 m above the
ground.
Express your answer using three significant figures and include
the appropriate units.

In the Olympic shot-put event, an athlete throws the shot with
an initial speed of 13.6 m/sm/s at a 40.0 ∘∘ angle from the
horizontal. The shot leaves her hand at a height of 1.80 mm above
the ground. (Figure 1)

If an arrow is shot upward on Mars with a speed of 68 m/s, its
height in meters t seconds later is given by y = 68t − 1.86t2.
(Round your answers to two decimal places.) (a) Find the average
speed over the given time intervals.
Estimate the speed when t = 1.
The trajectory of a rock thrown from a height with an initial
speed of 19.7 m/s is shown in the figure below. Evaluate the
magnitude of the gravitational field at the surface of the planet.
The planet has no atmosphere.
In the Olympic shotput event, an athlete throws the shot with an
initial speed of 13.0 m/s at a 44.0 ∘angle from the horizontal. The
shot leaves her hand at a height of 1.80 m above the ground.
How far does the shot travel?
Express your answer with the appropriate units.
Moving at an initial speed of vi = 2.00 m/s, Jimmy slides from a
height of h = 5.00 m down a straight playground slide, which is
inclined at θ = 55° above the horizontal. At the bottom of the
slide, Jimmy is moving at vf = 9.00 m/s. By determining the change
in mechanical energy, calculate the coefficient of kinetic friction
between Jimmy and the slide.
A blue ball is thrown upward with an initial speed of 24.3 m/s,
from a height of 0.9 meters above the ground. 3 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 8.2 m/s from a height of 33.3 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.

A blue ball is thrown upward with an initial speed of 22.2 m/s,
from a height of 0.5 meters above the ground. 2.7 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 10.7 m/s from a height of 26.9 meters above the ground.
The force of gravity due to the earth results in the balls each

A red ball is thrown down with an initial speed of 1.4 m/s from
a height of 29 meters above the ground. Then, 0.6 seconds after the
red ball is thrown, a blue ball is thrown upward with an initial
speed of 25.6 m/s, from a height of 1 meters above the ground. The
force of gravity due to the earth results in the balls each having
a constant downward acceleration of 9.81 m/s2.
