Question

A rocket was launched at angle 70° with initial velocity of 48m/s. Calculate the time of flight, time to reach maximum height, range, maximum height reached, horizontal and vertical displacement at t=2.6s, how long does it take the rocket to cover a vertical distance of 60m.

Answer 1

a. The time of flight is $T\approx9.2s$

b. The time to reach maximum heght is $t_1\approx4.6s$

c. The range is $S \approx151m$

d. The maximum height reached is $H \approx104m$

e. The horizontal and vertcal displasement at $t\approx2.6s$ is $x\approx43m$ , $y\approx84m$

f. The time to cover a vertical distance of 60m is $t_2\approx1.6s$
