When striking, the pike, a predatory fish, can accelerate from rest to a speed of 3.9 m/sm/s in 0.13 ss . what is the accelation of the pike during the strike? How for does the pike move during the strike?

An object is thrown straight up in the air with initial speed 20. 0 m/s.What are the velocity and acceleration of the object at its maximum height? Positive y points upward. Ov = 0 m/s, a = 9.81 m/s? Ov%3D -20.0 т/s, a — — 9.81 m/s* v = 20. 0 m/s, a = - 9. 81 m/s? Ov = 0 m/s, a = -9. 81 m/s² Ov= Оv%3D 20.0 m/s, a — 9. 81 m/s? Ov = -20.0 m/s, a = 9. 81 m/s²

A position function is given by F(t)= (10m+20t)i-5t²j. What is the velocity of the object it describes at t=2.0s? Using the same position function as the previous problem, what is the acceleration function? Using the same position function again, make an accurate plot of the object's trajectory over the first two seconds of flight. What's the lowest speed of the object in the prior problem in that time interval? I

This graph shows the position of a particle as a function of time. What is its instantaneous velocity at t = 7 s? x (m), 12 1(s) 6. 2 O 3 m/s -3 m/s O 12 m/s O -12 m/s O Need additional information

A certain volcano on the Earth can eject rocks vertically to a maximum height H. How high (in terms of H) would these rocks go if a volcano on a planetary object ejected them with the same initial velocity? The accelerations due to the gravity on the Earth and the planetary object are 9.8m/s² and 3.1 m/s?, respectively. Neglect the effect of the air on both planets. 답:

The height above the ground of a drone is given by h = 3.50 t³, where h is in meters and t is in seconds. Calculate at t = 2.50 s (a) the height of the drone above the ground and (b) the velocity of the drone. At this time (t = 2.50 s) the drone releases a package (c) how long does it take the package to reach the ground? Include a complete diagram of the situation.
