In a lab investigation one group of students group A measures the speed of a 0.1 kg toy car to be 2.5 m/s at the bottom of the ramp. another group of students Group B measures the speed of the car to be 3 m/s at the bottom of the ramp. The car's starting position at the top of the ramp is 1 M High 1.calculate the kinetic energy of the car for group A.

2. calculate the kinetic energy of the car for Group B

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?

What was the purpose of the apollo program? to put a man in orbit to launch a spy satellite to launch a space station to put man on the moon
