PLEASE ANSWER PARTS A, B, C, D, AND E.

A rocket is launched straight up with a constant acceleration of 25 m/s2. Six seconds after liftoff, a bolt falls off the side of the rocket.

(a) Determine the velocity of the bolt just before it falls off the side of the rocket.

(b) Determine the altitude of the bolt (measured from the ground) just before it falls off the side of the rocket.

(c) How long is the bolt in the air (from the instant it falls off the rocket to just before it hits the ground below)?

(d) What is the maximum altitude reached by the bolt?

(e) What is the velocity of the bolt just before it hits the ground?

Expert Solution

(a)v= 91.2 m/s vertically upwards

(b) altitude h= 273.6 m ( from ground)

(c) Time for it stayed in air = T= 27.2410 sec

(d) maximum reached H max= 697.9592 m

(e) velocity with which it hit ground = 116.9615 m/s or on rounding off= 117 m/s

A 1000 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 3600 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16 s?

A rocket is launched straight up. It contains two stages (Stage 1 and Stage 2) of solid rocket fuel that are designed to burn for 10.0 and 5.0 s, respectively, with no time interval between them. In Stage 1, the rocket fuel provides a net upward acceleration of 18 m/s2. In Stage 2, the net upward acceleration is 13 m/s2. Neglecting air resistance, calculate the maximum altitude above the surface of Earth of the payload and the time required for...
