During a test, a rocket travels upward at 75m/s, and when it is 40mfrom the ground its engine fails. Determine the maximum heightreached by the rocket and its speed just before it hits the ground.Neglect the effects of air resistance.
A penny is dropped from the observation deck of the Empire State building (215.0 m above ground). With what velocity would it strike the ground if air resistance were negligible? Assume the free-fall acceleration g = 9.80 m/s2. Ignore air resistance. If the velocity is downward, enter a negative value and if the velocity is upward, enter a positive value. answer in m/s

A) You are driving at a constant velocity of magnitude v0 when you notice a garbagecan on the road in front of you. At that moment, the distance between the garbage can and thefront of the car is d. A time t after noticing the garbage can, you apply the brakes and slow downat a constant rate before coming to a halt just before the garbage can. B) Find the magnitude of ax, the acceleration of the car after the brakes are applied, in terms ofthe variables d, t, and v0 You should have found in part B. that ax = v20C) 2(d−v0t). Based on this expression, what happensto ax if t increases and all the other variables remain constant?i) decreases because it is inversely proportional to a linear function of t that increases as t increases.ii) increases because it is inversely proportional to a linear function of t that increases as t increases.iii) increases because it is a linear function of t.iv) decreases because it is inversely proportional to a linear function of t that decreases as t…

Consider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance. b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.

When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is au = -g - kv², while the acceleration when the ball is moving downward is ad=-g+kv², where k is a positive constant and v is the speed in meters per second. If the ball is thrown upward with an initial speed of 40 m/s, determine the time tu from ground to apex and the time to from apex to ground. Take k to be 0.006 m¹ and assume that g is constant. au=-g-kv² Answers: tu = td = i i 40 m/s ad=-g+kv² S S h
