(a)
To find: The instantaneous velocity of the arrow after 1 second.
(a)
Answer to Problem 37E
56.34 m/s
Explanation of Solution
Given: Velocity on the moon If an arrow is shot upwards on the moon with a velocity of 58 m/s, its height ( in meters) after t seconds is given by
The relation of height and time of an arrow.
Differentiate w.r.t t
Put t=1
Hence, the instantaneous velocity of an arrow after 1 second would be 56.34 m/s.
(b)
To find: The instantaneous velocity of the arrow after a second.
(b)
Answer to Problem 37E
(58-1. 66a ) m/s
Explanation of Solution
Given: Velocity on the moon If an arrow is shot upwards on the moon with a velocity of 58 m/s, its height ( in meters) after t seconds is given by
The relation of height and time of an arrow.
Differentiate w.r.t t
Put t=a
Hence, the instantaneous velocity of an arrow after a second would be (58-1. 66a ) m/s.
(c)
To find: The time when arrow hit the moon.
(c)
Answer to Problem 37E
69.88 seconds.
Explanation of Solution
Given: Velocity on the moon If an arrow is shot upwards on the moon with a velocity of 58 m/s, its height ( in meters) after t seconds is given by
The relation of height and time of an arrow.
Put H =0
Hence, After 69.88 seconds arrow will hit the moon.
(d)
To find: The instantaneous velocity of the arrow after a second.
(d)
Answer to Problem 37E
58 m/s
Explanation of Solution
Given: Velocity on the moon If an arrow is shot upwards on the moon with a velocity of 58 m/s, its height ( in meters) after t seconds is given by
The relation of height and time of an arrow.
Differentiate w.r.t t
Put t=69.88
Hence, the arrow hit the moon with 58 m/s.
