A car starts from rest and moves around a circular track of
radius 32.0 m. Its speed increases at the constant rate of 0.550
m/s2. (a) What is the magnitude of its
net linear acceleration 19.0 s later? (b) What
angle does this net acceleration vector make with the car's
velocity at this time?

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 49.0 m/s2 . The acceleration period lasts for time 7.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 .

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 29.4m/s2 . The acceleration period lasts for time 9.00s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 . Write your answer numerically in units of meters.

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 53.9 m/s2m/s2 . The acceleration period lasts for time 8.00 ss until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height ymax reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s2 . Write your answer numerically in units of meters.

A rocket moves upward starting from rest with an acceleration of 20 m/s^2 for 5 s. It runs out of fuel at the end of this 5 s and continues to move upward, acted upon only by gravity. How high does it rise? Find the velocity of the rocket just before it hits the ground and how long it is in the air?
A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration...
A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 53.9 m/s^2. The acceleration period lasts for time 5.00 s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height y_max reached by the rocket. Ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 m/s^2. Write your answer numerically in units of meters.

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.

7. Two train cars are on a straight, horizontal track. The car A starts at rest and is put in motion with a constant acceleration of 2.00 m/s2. This car A moves toward the car B that is 25.0 m away. The car B is moving in same direction as car A with an initial velocity of 4.5 m/s and is traveling with a constant acceleration of -1.50 m/s2 a) Where will the cars collide? b) How long will it...
