Question

I need these question to be done asap.

In (Figure 1) , what value of Fmax gives an impulse of 7.8 Ns?

Express your answer to two significant figures and include the appropriate units.

Q2:

Far in space, where gravity is negligible, a 495 kg rocket traveling at 95.0 m/s fires its engines. The figure (Figure 1) shows the thrust force as a function of time. The mass lost by the rocket during these 30 s is negligible.

Part A

What impulse does the engine impart to the rocket?

Part B

At what time does the rocket reach its maximum speed?

Part C

What is the maximum speed of the rocket?

Fmax 0D t (ms) 0 2 4 6 8 10

Explanation / Answer

The area under the Force time graph gives impulse.

For the given graph, impulse is:

J = 2 x Ara of traingles + Area of rectangle

J = 2 x 1/2 x 2 x 10^-3 x Fmax + F(max) x 4 x 10^-3

7.8 N-s = 6 x 10^-3 F(max) = (0.006)F(max)

F(max) = 7.8/0.006 = 1300 N

Hence, F(max) = 1300 N
