Answer 1

Answer #1

given that

final velocity v_f = 115 m/s

initial velocity v_i = 12 m/s

displacement s = 225 m

using kinematics equation v_f² = v_i² + 2as

115² - 12² = 2a(225)

a= 29.07 m/s²

A rocket test sled accelerates at a constant rate of 15 m/s2 from rest while moving along a straight track. The rocket engine turns off instantly when the sled reaches a speed 30 m/s. The sled then moves freely (acceleration = 0) for a period of 5 s, after which the brakes are automatically applied giving a constant deceleration of -25 m/s2. What is the total time that the sled is moving?

A toy rocket is launched from rest at an angle of 43 degrees and follows a straight line path as long as the engine is burning. The engine burns for 9.4 seconds with an acceleration of 5.2 m/s^2. Once the engine turns off, the rocket is considered a projectile. How far from the launch point does the rocket land. Use the Kinematic Equations to solve the problem Xf=Xi+Vix(t)+1/2axt2 Vfx=Vix+axt Vfx2=Vix2+2ax (Xf -Xi)
